3002b7a318 Staging driver changes for 6.1-rc1 
Here is the large set of staging driver changes for 6.1-rc1.
 
 Nothing really interesting in here at all except we deleted a driver
 (fwserial) as no one had been using it for a long time.  Other than
 that, just the normal cleanups and minor fixes:
   - rtl8723bs driver cleanups
   - loads of r8188eu driver cleanups, making the driver smaller and
     fixing up some firmware dependency issues.
   - vt6655 driver cleanups.
   - lots of other small staging driver cleanups.
 
 All of these have been in linux-next for a while with no reported
 issues.

1f3d5477b9 cifs: secmech: use shash_desc directly, remove sdesc 
The struct sdesc is just a wrapper around shash_desc, with exact same
memory layout. Replace the hashing TFMs with shash_desc as it's what's
passed to the crypto API anyway.

Also remove the crypto_shash pointers as they can be accessed via
shash_desc->tfm (and are actually only used in the setkey calls).

Adapt cifs_{alloc,free}_hash functions to this change.

The log :
"genirq: Flags mismatch irq 0. 00000080 (virtio418) vs. 00015a00 (timer)"
was printed because of the irq 0 is used by timer exclusive,and when
vp_find_vqs call vp_find_vqs_msix and returns false twice (for
whatever reason), then it will call vp_find_vqs_intx as a fallback.
Because vp_dev->pci_dev->irq is zero, we request irq 0 with
flag IRQF_SHARED, and get a backtrace like above.

According to PCI spec about "Interrupt Pin" Register (Offset 3Dh):
"The Interrupt Pin register is a read-only register that identifies the
 legacy interrupt Message(s) the Function uses. Valid values are 01h, 02h,
 03h, and 04h that map to legacy interrupt Messages for INTA,
 INTB, INTC, and INTD respectively. A value of 00h indicates that the
 Function uses no legacy interrupt Message(s)."

So if vp_dev->pci_dev->pin is zero, we should not request legacy
interrupt.

The spec says:
mtu only exists if VIRTIO_NET_F_MTU is set
The mac address field always exists (though
is only valid if VIRTIO_NET_F_MAC is set)

So vdpa_dev_net_config_fill() should read MTU and MAC
conditionally on the feature bits.

 	- thunderbolt/USB4 devices supported a bit better than before,
 	  and some new ids to enable new hardware devices
 	- USB gadget uvc updates for newer video formats and better v4l
 	  integration (the v4l portions were acked by those maintainers)
 	- typec updates for tiny issues and more typec drivers for new
 	  chips.
 	- xhci tiny updates for minor issues
 	- big usb-serial ftdi_sio driver update to handle new devices
 	  better
 	- lots of tiny dwc3 fixes and updates for the IP block that is
 	  showing up everywhere these days
 	- dts updates for new devices being supported
 	- other tiny janitorial and cleanups fixes for lots of different
 	  USB drivers.  Full details are in the shortlog.
 
 All of these have been in linux-next for a while with no reported

6181073dd6 TTY/Serial driver update for 6.1-rc1 
Here is the big set of TTY and Serial driver updates for 6.1-rc1.
 
 Lots of cleanups in here, no real new functionality this time around,
 with the diffstat being that we removed more lines than we added!
 
 Included in here are:
 	- termios unification cleanups from Al Viro, it's nice to
 	  finally get this work done
 	- tty serial transmit cleanups in various drivers in preparation
 	  for more cleanup and unification in future releases (that work
 	  was not ready for this release.)
 	- n_gsm fixes and updates
 	- ktermios cleanups and code reductions
 	- dt bindings json conversions and updates for new devices
 	- some serial driver updates for new devices
 	- lots of other tiny cleanups and janitorial stuff.  Full
 	  details in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

bbff39cc6c hugetlb: allocate vma lock for all sharable vmas 
The hugetlb vma lock was originally designed to synchronize pmd sharing. 
As such, it was only necessary to allocate the lock for vmas that were
capable of pmd sharing.  Later in the development cycle, it was discovered
that it could also be used to simplify fault/truncation races as described
in [1].  However, a subsequent change to allocate the lock for all vmas
that use the page cache was never made.  A fault/truncation race could
leave pages in a file past i_size until the file is removed.

Remove the previous restriction and allocate lock for all VM_MAYSHARE
vmas.  Warn in the unlikely event of allocation failure.

ecfbd73387 hugetlb: take hugetlb vma_lock when clearing vma_lock->vma pointer 
hugetlb file truncation/hole punch code may need to back out and take
locks in order in the routine hugetlb_unmap_file_folio().  This code could
race with vma freeing as pointed out in [1] and result in accessing a
stale vma pointer.  To address this, take the vma_lock when clearing the
vma_lock->vma pointer.

131a79b474 hugetlb: fix vma lock handling during split vma and range unmapping 
Patch series "hugetlb: fixes for new vma lock series".

In review of the series "hugetlb: Use new vma lock for huge pmd sharing
synchronization", Miaohe Lin pointed out two key issues:

1) There is a race in the routine hugetlb_unmap_file_folio when locks
   are dropped and reacquired in the correct order [1].

2) With the switch to using vma lock for fault/truncate synchronization,
   we need to make sure lock exists for all VM_MAYSHARE vmas, not just
   vmas capable of pmd sharing.

These two issues are addressed here.  In addition, having a vma lock
present in all VM_MAYSHARE vmas, uncovered some issues around vma
splitting.  Those are also addressed.

[1] https://lore.kernel.org/linux-mm/01f10195-7088-4462-6def-909549c75ef4@huawei.com/


This patch (of 3):

The hugetlb vma lock hangs off the vm_private_data field and is specific
to the vma.  When vm_area_dup() is called as part of vma splitting, the
vma lock pointer is copied to the new vma.  This will result in issues
such as double freeing of the structure.  Update the hugetlb open vm_ops
to allocate a new vma lock for the new vma.

The routine __unmap_hugepage_range_final unconditionally unset VM_MAYSHARE
to prevent subsequent pmd sharing.  hugetlb_vma_lock_free attempted to
anticipate this by checking both VM_MAYSHARE and VM_SHARED.  However, if
only VM_MAYSHARE was set we would miss the free.  With the introduction of
the vma lock, a vma can not participate in pmd sharing if vm_private_data
is NULL.  Instead of clearing VM_MAYSHARE in __unmap_hugepage_range_final,
free the vma lock to prevent sharing.  Also, update the sharing code to
make sure vma lock is indeed a condition for pmd sharing. 
hugetlb_vma_lock_free can then key off VM_MAYSHARE and not miss any vmas.

14aa8b2d5c mm/mglru: don't sync disk for each aging cycle 
wakeup_flusher_threads() was added under the assumption that if a system
runs out of clean cold pages, it might want to write back dirty pages more
aggressively so that they can become clean and be dropped.

However, doing so can breach the rate limit a system wants to impose on
writeback, resulting in early SSD wearout.

62e6e5940c SCSI misc on 20221007 
Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr,
 mpt3sas, target); the biggest change (from my biased viewpoint) being
 that the mpi3mr now attached to the SAS transport class, making it the
 first fusion type device to do so.  Beyond the usual bug fixing and
 security class reworks, there aren't a huge number of core changes.

   libata-eh and the pata_macio driver and to fix typos in comments
   (from Jinpeng, Shaomin, Ye)

 - Some code simplifications and macro renaming (for clarity) in various
   functions of libata-core (from me)

 - Add a missing check for a potential failure of sata_scr_read() in
   sata_print_link_status() (from Li)

 - Cleanup of libata Kconfig PATA_PLATFORM and PATA_OF_PLATFORM options
   (from Lukas)

 - Cleanups of ata dt-bindings and improvements of libahci_platform,
   ahci and libahci code (from Serge)

 - New driver for Synopsys AHCI SATA controllers, based of the generic
   ahci code (from Serge). One compilation warning fix is added for this
   driver (from me)

 - Several fixes to macros used to discover a drive capabilities to be
   consistent with the ACS specifications (from Niklas)

 - A couple of simplifcations to some libata functions, removing
   unnecessary arguments (from Niklas)

 - An improvements to libata-eh code to avoid unnecessary link reset
   when revalidating a drive after a failed command. In practice, this
   extra, unneeded reset, reset does not cause any arm beyond slightly
   slowing down error recovery (from Niklas)

Pull io_uring updates from Jens Axboe:

 - Add supported for more directly managed task_work running.

   This is beneficial for real world applications that end up issuing
   lots of system calls as part of handling work. Normal task_work will
   always execute as we transition in and out of the kernel, even for
   "unrelated" system calls. It's more efficient to defer the handling
   of io_uring's deferred work until the application wants it to be run,
   generally in batches.

   As part of ongoing work to write an io_uring network backend for
   Thrift, this has been shown to greatly improve performance. (Dylan)

 - Add IOPOLL support for passthrough (Kanchan)

 - Improvements and fixes to the send zero-copy support (Pavel)

 - Partial IO handling fixes (Pavel)

 - CQE ordering fixes around CQ ring overflow (Pavel)

 - Support sendto() for non-zc as well (Pavel)

e60d640742 virtio_blk: add SECURE ERASE command support 
Support for the VIRTIO_BLK_F_SECURE_ERASE VirtIO feature.

A device that offers this feature can receive VIRTIO_BLK_T_SECURE_ERASE
commands.

A device which supports this feature has the following fields in the
virtio config:

- max_secure_erase_sectors
- max_secure_erase_seg
- secure_erase_sector_alignment

max_secure_erase_sectors and secure_erase_sector_alignment are expressed
in 512-byte units.

Every secure erase command has the following fields:

- sectors: The starting offset in 512-byte units.
- num_sectors: The number of sectors.

c1ca352d37 vp_vdpa: support feature provisioning 
This patch allows the device features to be provisioned via
netlink. This is done by:

1) validating the provisioned features to be a subset of the parent
   features.
2) clearing the features that is not wanted by the userspace

For example:

# vdpa mgmtdev show
pci/0000:02:00.0:
  supported_classes net
  max_supported_vqs 3
  dev_features CSUM GUEST_CSUM CTRL_GUEST_OFFLOADS MAC GUEST_TSO4
  GUEST_TSO6 GUEST_ECN GUEST_UFO HOST_TSO4 HOST_TSO6 HOST_ECN HOST_UFO
  MRG_RXBUF STATUS CTRL_VQ CTRL_RX CTRL_VLAN CTRL_RX_EXTRA
  GUEST_ANNOUNCE CTRL_MAC_ADDR RING_INDIRECT_DESC RING_EVENT_IDX
  VERSION_1 ACCESS_PLATFORM

1) provision vDPA device with all features that are supported by the virtio-pci

# vdpa dev add name dev1 mgmtdev pci/0000:02:00.0
# vdpa dev config show
dev1: mac 52:54:00:12:34:56 link up link_announce false mtu 65535
  negotiated_features CSUM GUEST_CSUM CTRL_GUEST_OFFLOADS MAC
  GUEST_TSO4 GUEST_TSO6 GUEST_ECN GUEST_UFO HOST_TSO4 HOST_TSO6
  HOST_ECN HOST_UFO MRG_RXBUF STATUS CTRL_VQ CTRL_RX CTRL_VLAN
  GUEST_ANNOUNCE CTRL_MAC_ADDR RING_INDIRECT_DESC RING_EVENT_IDX
  VERSION_1 ACCESS_PLATFORM

2) provision vDPA device with a subset of the features

# vdpa dev add name dev1 mgmtdev pci/0000:02:00.0 device_features 0x300020000
# dev1: mac 52:54:00:12:34:56 link up link_announce false mtu 65535

90fea5a800 vdpa: device feature provisioning 
This patch allows the device features to be provisioned through
netlink. A new attribute is introduced to allow the userspace to pass
a 64bit device features during device adding.

This provides several advantages:

- Allow to provision a subset of the features to ease the cross vendor
  live migration.
- Better debug-ability for vDPA framework and parent.

4959aebba8 virtio-net: use mtu size as buffer length for big packets 
Currently add_recvbuf_big() allocates MAX_SKB_FRAGS segments for big
packets even when GUEST_* offloads are not present on the device.
However, if guest GSO is not supported, it would be sufficient to
allocate segments to cover just up the MTU size and no further.
Allocating the maximum amount of segments results in a large waste of
buffer space in the queue, which limits the number of packets that can
be buffered and can result in reduced performance.

Therefore, if guest GSO is not supported, use the MTU to calculate the
optimal amount of segments required.

Below is the iperf TCP test results over a Mellanox NIC, using vDPA for
1 VQ, queue size 1024, before and after the change, with the iperf
server running over the virtio-net interface.

MTU(Bytes)/Bandwidth (Gbit/s)
             Before   After
  1500        22.5     22.4
  9000        12.8     25.9

And result of queue size 256.
MTU(Bytes)/Bandwidth (Gbit/s)
             Before   After
  9000        2.15     11.9

With this patch no degradation is observed with multiple below tests and
feature bit combinations. Results are summarized below for q depth of
1024. Interface MTU is 1500 if MTU feature is disabled. MTU is set to 9000
in other tests.
