487fae09d7 NFS: Add a mount option to make ENETUNREACH errors fatal
If the NFS client was initially created in a container, and that
container is torn down, there is usually no possibity to go back and
destroy any NFS clients that are hung because their virtual network
devices have been unlinked.

Add a flag that tells the NFS client that in these circumstances, it
should treat ENETDOWN and ENETUNREACH errors as fatal to the NFS client.

The option defaults to being on when the mount happens from inside a net
namespace that is not "init_net".

adcc0aef9e NFS: Use NFSv4.2's OFFLOAD_STATUS operation
We've found that there are cases where a transport disconnection
results in the loss of callback RPCs. NFS servers typically do not
retransmit callback operations after a disconnect.

This can be a problem for the Linux NFS client's current
implementation of asynchronous COPY, which waits indefinitely for a
CB_OFFLOAD callback. If a transport disconnect occurs while an async
COPY is running, there's a good chance the client will never get the
completing CB_OFFLOAD.

Fix this by implementing the OFFLOAD_STATUS operation so that the
Linux NFS client can probe the NFS server if it doesn't see a
CB_OFFLOAD in a reasonable amount of time.

This patch implements a simplistic check. As future work, the client
might also be able to detect whether there is no forward progress on
the request asynchronous COPY operation, and CANCEL it.

43502f6e8d NFS: fix open_owner_id_maxsz and related fields.
A recent change increased the size of an NFSv4 open owner, but didn't
increase the corresponding max_sz defines.  This is not know to have
caused failure, but should be fixed.

This patch also fixes some relates _maxsz fields that are wrong.

Note that the XXX_owner_id_maxsz values now are only the size of the id
and do NOT include the len field that will always preceed the id in xdr
encoding.  I think this is clearer.

Pull fsnotify reverts from Jan Kara:
 "Syzbot has found out that fsnotify HSM events generated on page fault
  can be generated while we already hold freeze protection for the
  filesystem (when you do buffered write from a buffer which is mmapped
  file on the same filesystem) which violates expectations for HSM
  events and could lead to deadlocks of HSM clients with filesystem
  freezing.

  Since it's quite late in the cycle we've decided to revert changes
  implementing HSM events on page fault for now and instead just
  generate one event for the whole range on mmap(2) so that HSM client
  can fetch the data at that moment"

Pull x86 platform driver fixes from Ilpo Järvinen:
 "Fixes and new HW support.

  The diff is a bit larger than I'd prefer at this point due to
  unwinding the amd/pmf driver's error handling properly instead of
  calling a deinit function that was a can full of worms.

  Summary:

   - amd/pmf:
       - Fix error handling in amd_pmf_init_smart_pc()

Merge tag 'gpio-fixes-for-v6.14-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio fixes from Bartosz Golaszewski:
 "The first fix is a backport from my v6.15-rc1 queue that turned out to
  be needed in v6.14 as well but as the former diverged from my fixes
  branch I had to adjust the patch a bit.

  The second one fixes a regression observed in user-space where closing
  a file descriptor associated with a GPIO device results in a ~10ms
  delay due to the atomic notifier calling rcu_synchronize() when
  unregistering.

  Summary:

   - don't check the return value of gpio_chip::get_direction() when
     registering a GPIO chip

   - use raw notifier for line state events"

b1144bc7cb sound fixes for 6.14-rc7
A collection of last-minute fixes.  Most of them are for ASoC, and
 the only one core fix is for reverting the previous change, while
 the rest are all device-specific quirks and fixes, which should be
 relatively safe to apply.
