So all files which created in 'do_blk_trace_setup' are removed, and

Commit c347a787e34cb (drbd: set ->bi_bdev in drbd_req_new) moved a
bio_set_dev call (which has since been removed) to "earlier", from
drbd_request_prepare to drbd_req_new.
The problem is that this accesses device->ldev->backing_bdev, which is
not NULL-checked at this point. When we don't have an ldev (i.e. when
the DRBD device is diskless), this leads to a null pointer deref.
So, only allocate the private_bio if we actually have a disk. This is
also a small optimization, since we don't clone the bio to only to
immediately free it again in the diskless case.

Recent commit 52fde2c07da6 ("nvme: set dma alignment to dword") has
caused a regression on our platform.
It turned out that the nvme_get_log() method invocation caused the
nvme_hwmon_data structure instance corruption. In particular the
nvme_hwmon_data.ctrl pointer was overwritten either with zeros or with
garbage. After some research we discovered that the problem happened
even before the actual NVME DMA execution, but during the buffer mapping.
Since our platform is DMA-noncoherent, the mapping implied the cache-line
invalidations or write-backs depending on the DMA-direction parameter.
In case of the NVME SMART log getting the DMA was performed
from-device-to-memory, thus the cache-invalidation was activated during
the buffer mapping. Since the log-buffer isn't cache-line aligned, the
cache-invalidation caused the neighbour data to be discarded. The
neighbouring data turned to be the data surrounding the buffer in the
framework of the nvme_hwmon_data structure.
In order to fix that we need to make sure that the whole log-buffer is
defined within the cache-line-aligned memory region so the
cache-invalidation procedure wouldn't involve the adjacent data. One of
the option to guarantee that is to kmalloc the DMA-buffer [1]. Seeing the
rest of the NVME core driver prefer that method it has been chosen to fix
this problem too.
Note after a deeper researches we found out that the denoted commit wasn't
a root cause of the problem. It just revealed the invalidity by activating
the DMA-based NVME SMART log getting performed in the framework of the
NVME hwmon driver. The problem was here since the initial commit of the
driver.

NVMe uses PRPs for data transfers and has no specific limit for a single
DMA segement. Limiting the size will cause problems because the block
layer assumes PRP-ish devices using a virt boundary mask don't have a
segment limit. And while this is true, we also really need to tell the
DMA mapping layer about it, otherwise dma-debug will trip over it.

When we revalidate paths as part of ns size change (as of commit
e7d65803e2bb), it is possible that during the path revalidation, the
only paths that is IO capable (i.e. optimized/non-optimized) are the
ones that ns resize was not yet informed to the host, which will cause
inflight requests to be requeued (as we have available paths but none
are IO capable). These requests on the requeue list are waiting for
someone to resubmit them at some point.
The IO capable paths will eventually notify the ns resize change to the
host, but there is nothing that will kick the requeue list to resubmit
the queued requests.
Fix this by always kicking the requeue list, and if no IO capable path
exists, these requests will be queued again.
A typical log that indicates that IOs are requeued:

When we delete a controller, we execute the following:
1. nvme_stop_ctrl() - stop some work elements that may be
inflight or scheduled (specifically also .stop_ctrl
which cancels ctrl error recovery work)
2. nvme_remove_namespaces() - which first flushes scan_work
to avoid competing ns addition/removal
3. continue to teardown the controller
However, if err_work was scheduled to run in (1), it is designed to
cancel any inflight I/O, particularly I/O that is originating from ns
scan_work in (2), but because it is cancelled in .stop_ctrl(), we can
prevent forward progress of (2) as ns scanning is blocking on I/O
(that will never be cancelled).
The race is:
1. transport layer error observed -> err_work is scheduled
2. scan_work executes, discovers ns, generate I/O to it
3. nvme_ctop_ctrl() -> .stop_ctrl() -> cancel_work_sync(err_work)
- err_work never executed
4. nvme_remove_namespaces() -> flush_work(scan_work)
--> deadlock, because scan_work is blocked on I/O that was supposed
to be cancelled by err_work, but was cancelled before executing (see
stack trace [1]).
Fix this by flushing err_work instead of cancelling it, to force it
to execute and cancel all inflight I/O.

request_queue->queue_flags is unsigned long, which is 8-bytes on
64-bit architectures. Most queue flag modifications occur through
bit field helpers, but default flags can be logically OR'd via the
QUEUE_FLAG_MQ_DEFAULT mask. If this mask happens to include bit 31,
the assignment can sign extend the field and set all upper 32 bits.
This exact problem has been observed on a downstream kernel that
happens to use bit 31 for QUEUE_FLAG_NOWAIT. This is not an
immediate problem for current upstream because bit 31 is not
included in the default flag assignment (and is not used at all,
actually). Regardless, fix up the QUEUE_FLAG_MQ_DEFAULT mask
definition to avoid the landmine in the future.

After the ucount rlimit code was merged a bunch of small but
siginificant bugs were found and fixed. At the time it was realized
that part of the problem was that while the ucount rlimits were very
similar to the oridinary ucounts (in being nested counts with limits)
the semantics were slightly different and the code would be less error
prone if there was less sharing. This is the long awaited cleanup
that should hopefully keep things more comprehensible and less error
prone for whoever needs to touch that code next.

Recently I had a conversation where it was pointed out to me that
SIGKILL sent to a tracee stropped in PTRACE_EVENT_EXIT is quite
difficult for a tracer to handle.
Keeping SIGKILL working after the process has been killed is pain
from an implementation point of view.
So since the debuggers don't want this behavior let's see if we can
remove this wart for the userspace API
If a regression is detected it should only need to be the last change
that is the reverted. The other two are just general cleanups that
make the last patch simpler.

am sending out early due to me travelling next week. There is a
lone mm patch for which Andrew gave an informal ack at
https://lore.kernel.org/linux-mm/20220817102500.440c6d0a3fce296fdf91bea6@linux-foundation.org.
I will send the bulk of ARM work, as well as other
architectures, at the end of next week.
ARM:
* Account stage2 page table allocations in memory stats.
x86:
* Account EPT/NPT arm64 page table allocations in memory stats.
* Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR accesses.
* Drop eVMCS controls filtering for KVM on Hyper-V, all known versions of
Hyper-V now support eVMCS fields associated with features that are
enumerated to the guest.
* Use KVM's sanitized VMCS config as the basis for the values of nested VMX
capabilities MSRs.
* A myriad event/exception fixes and cleanups. Most notably, pending
exceptions morph into VM-Exits earlier, as soon as the exception is
queued, instead of waiting until the next vmentry. This fixed
a longstanding issue where the exceptions would incorrecly become
double-faults instead of triggering a vmexit; the common case of
page-fault vmexits had a special workaround, but now it's fixed
for good.
* A handful of fixes for memory leaks in error paths.
* Cleanups for VMREAD trampoline and VMX's VM-Exit assembly flow.
* Never write to memory from non-sleepable kvm_vcpu_check_block()
* Selftests refinements and cleanups.
* Misc typo cleanups.
Generic:
* remove KVM_REQ_UNHALT

Pull EFI updates from Ard Biesheuvel:
"A bit more going on than usual in the EFI subsystem. The main driver
for this has been the introduction of the LoonArch architecture last
cycle, which inspired some cleanup and refactoring of the EFI code.
Another driver for EFI changes this cycle and in the future is
confidential compute.
The LoongArch architecture does not use either struct bootparams or DT
natively [yet], and so passing information between the EFI stub and
the core kernel using either of those is undesirable. And in general,
overloading DT has been a source of issues on arm64, so using DT for
this on new architectures is a to avoid for the time being (even if we
might converge on something DT based for non-x86 architectures in the
future). For this reason, in addition to the patch that enables EFI
boot for LoongArch, there are a number of refactoring patches applied
on top of which separate the DT bits from the generic EFI stub bits.
These changes are on a separate topich branch that has been shared
with the LoongArch maintainers, who will include it in their pull
request as well. This is not ideal, but the best way to manage the
conflicts without stalling LoongArch for another cycle.
Another development inspired by LoongArch is the newly added support
for EFI based decompressors. Instead of adding yet another
arch-specific incarnation of this pattern for LoongArch, we are
introducing an EFI app based on the existing EFI libstub
infrastructure that encapulates the decompression code we use on other
architectures, but in a way that is fully generic. This has been
developed and tested in collaboration with distro and systemd folks,
who are eager to start using this for systemd-boot and also for arm64
secure boot on Fedora. Note that the EFI zimage files this introduces
can also be decompressed by non-EFI bootloaders if needed, as the
image header describes the location of the payload inside the image,
and the type of compression that was used. (Note that Fedora's arm64
GRUB is buggy [0] so you'll need a recent version or switch to
systemd-boot in order to use this.)
Finally, we are adding TPM measurement of the kernel command line
provided by EFI. There is an oversight in the TCG spec which results
in a blind spot for command line arguments passed to loaded images,
which means that either the loader or the stub needs to take the
measurement. Given the combinatorial explosion I am anticipating when
it comes to firmware/bootloader stacks and firmware based attestation
protocols (SEV-SNP, TDX, DICE, DRTM), it is good to set a baseline now
when it comes to EFI measured boot, which is that the kernel measures
the initrd and command line. Intermediate loaders can measure
additional assets if needed, but with the baseline in place, we can
deploy measured boot in a meaningful way even if you boot into Linux
straight from the EFI firmware.
Summary:
- implement EFI boot support for LoongArch
- implement generic EFI compressed boot support for arm64, RISC-V and
LoongArch, none of which implement a decompressor today
- measure the kernel command line into the TPM if measured boot is in
effect

commit 8c5035dfbb94 ("blk-wbt: call rq_qos_add() after wb_normal is
initialized") moves wbt_set_write_cache() before rq_qos_add(), which
is wrong because wbt_rq_qos() is still NULL.
Fix the problem by removing wbt_set_write_cache() and setting 'rwb->wc'
directly. Noted that this patch also remove the redundant setting of
'rab->wc'.

late breaking reports that a patch series to rework clk rate range
support broke boot on some devices, so I've left that branch out of this
PR. Hopefully we can get to that next week, or punt on it and let it
bake another cycle. That means we don't really have any changes to the
core framework this time around besides a few typo fixes. Instead this
is all clk driver updates and fixes.
The usual suspects are here (again), with Qualcomm dominating the
diffstat. We look to have gained support for quite a few new Qualcomm
SoCs and Dmitry worked on updating many of the existing Qualcomm drivers
to use clk_parent_data. After that we have MediaTek drivers getting some
much needed updates, in particular to support GPU DVFS. There are also
quite a few Samsung clk driver patches, but that's mostly because there
was a maintainer change and so last release we missed some of those
patches.
Overall things look normal, but I'm slowly reviewing core framework code
nowadays and that shows given the rate range patches had to be yanked
last minute. Let's hope this situation changes soon.

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.
