ce7df05508 NFSD: Make the file_delayed_close workqueue UNBOUND
workqueue: nfsd_file_delayed_close [nfsd] hogged CPU for >13333us 8
	times, consider switching to WQ_UNBOUND

There's no harm in closing a cached file descriptor on another core.

f3734cc407 NFSD: use read_seqbegin() rather than read_seqbegin_or_lock()
The usage of read_seqbegin_or_lock() in nfsd_copy_write_verifier()
is wrong. "seq" is always even and thus "or_lock" has no effect,
this code can never take ->writeverf_lock for writing.

I guess this is fine, nfsd_copy_write_verifier() just copies 8 bytes
and nfsd_reset_write_verifier() is supposed to be very rare operation
so we do not need the adaptive locking in this case.

Yet the code looks wrong and sub-optimal, it can use read_seqbegin()
without changing the behaviour.

[ cel: Note also that it eliminates this Sparse warning:

fs/nfsd/nfssvc.c:360:6: warning: context imbalance in 'nfsd_copy_write_verifier' -
	different lock contexts for basic block

74fd48739d nfsd: new Kconfig option for legacy client tracking
We've had a number of attempts at different NFSv4 client tracking
methods over the years, but now nfsdcld has emerged as the clear winner
since the others (recoverydir and the usermodehelper upcall) are
problematic.

As a case in point, the recoverydir backend uses MD5 hashes to encode
long form clientid strings, which means that nfsd repeatedly gets dinged
on FIPS audits, since MD5 isn't considered secure. Its use of MD5 is not
cryptographically significant, so there is no danger there, but allowing
us to compile that out allows us to sidestep the issue entirely.

As a prelude to eventually removing support for these client tracking
methods, add a new Kconfig option that enables them. Mark it deprecated
and make it default to N.

3ee29a4474 ipvlan: Remove usage of the deprecated ida_simple_xx() API
ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

This is less verbose.

Note that the upper bound of ida_alloc_range() is inclusive while the one
of ida_simple_get() was exclusive. So calls have been updated accordingly.

6d039984c1 smb: client: stop revalidating reparse points unnecessarily
Query dir responses don't provide enough information on reparse points
such as major/minor numbers and symlink targets other than reparse
tags, however we don't need to unconditionally revalidate them only
because they are reparse points.  Instead, revalidate them only when
their ctime or reparse tag has changed.

For instance, Windows Server updates ctime of reparse points when
their data have changed.

6ebfede8d5 cifs: Pass unbyteswapped eof value into SMB2_set_eof()
Change SMB2_set_eof() to take eof as CPU order rather than __le64 and pass
it directly rather than by pointer.  This moves the conversion down into
SMB_set_eof() rather than all of its callers and means we don't need to

ac631873c9 net: ethernet: cortina: Drop TSO support
The recent change to allow large frames without hardware checksumming
slotted in software checksumming in the driver if hardware could not
do it.

This will however upset TSO (TCP Segment Offloading). Typical
error dumps includes this:

skb len=2961 headroom=222 headlen=66 tailroom=0
(...)
WARNING: CPU: 0 PID: 956 at net/core/dev.c:3259 skb_warn_bad_offload+0x7c/0x108
gemini-ethernet-port: caps=(0x0000010000154813, 0x00002007ffdd7889)

And the packets do not go through.

The TSO implementation is bogus: a TSO enabled driver must propagate
the skb_shinfo(skb)->gso_size value to the TSO engine on the NIC.

Drop the size check and TSO offloading features for now: this
needs to be fixed up properly.

After this ethernet works fine on Gemini devices with a direct connected
PHY such as D-Link DNS-313.

Also tested to still be working with a DSA switch using the Gemini
ethernet as conduit interface.

Fix rxrpc_cleanup_ring() to use rxrpc_purge_queue() rather than

updated when a failed call is cleaned up.

Without this rmmod may hang waiting for rxrpc_n_rx_skbs to become zero.

a460f4a684 mlxbf_gige: Enable the GigE port in mlxbf_gige_open
At the moment, the GigE port is enabled in the mlxbf_gige_probe
function. If the mlxbf_gige_open is not executed, this could cause
pause frames to increase in the case where there is high backgroud
traffic. This results in clogging the port.
So move enabling the OOB port to mlxbf_gige_open.

ef210ef85d mlxbf_gige: Fix intermittent no ip issue
Although the link is up, there is no ip assigned on setups with high background
traffic. Nothing is transmitted nor received. The RX error count keeps on
increasing. After several minutes, the RX error count stagnates and the
GigE interface finally gets an ip.

The issue is that mlxbf_gige_rx_init() is called before phy_start().
As soon as the RX DMA is enabled in mlxbf_gige_rx_init(), the RX CI reaches the max
of 128, and becomes equal to RX PI. RX CI doesn't decrease since the code hasn't
ran phy_start yet.
Bring the PHY up before starting the RX.

363096a27f nfp: flower: Remove usage of the deprecated ida_simple_xx() API
ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

This is less verbose.

Note that the upper bound of ida_alloc_range() is inclusive while the one
of ida_simple_get() was exclusive.
So NFP_FL_LAG_GROUP_MAX has been decreased by 1. It now better watch the
comment stating that "1 to 31 are valid".

The only other user of NFP_FL_LAG_GROUP_MAX has been updated accordingly in
nfp_fl_lag_put_unprocessed().

a3368e1186 i2c: core: Fix atomic xfer check for non-preempt config
Since commit aa49c90894 ("i2c: core: Run atomic i2c xfer when
!preemptible"), the whole reboot/power off sequence on non-preempt kernels
is using atomic i2c xfer, as !preemptible() always results to 1.

During device_shutdown(), the i2c might be used a lot and not all busses
have implemented an atomic xfer handler. This results in a lot of
avoidable noise, like:

[   12.687169] No atomic I2C transfer handler for 'i2c-0'
[   12.692313] WARNING: CPU: 6 PID: 275 at drivers/i2c/i2c-core.h:40 i2c_smbus_xfer+0x100/0x118
...

Fix this by allowing non-atomic xfer when the interrupts are enabled, as
it was before.
