test_progs -t bind_perm,bpf_obj_pinning/mounted-str-rel fails when
the selftests directory is mounted under /mnt, which is a reasonable
thing to do when sharing the selftests residing on the host with a
virtual machine, e.g., using 9p.

The reason is that cgroup2 is mounted at /mnt and not unmounted,
causing subsequent tests that need to access the selftests directory
to fail.

Fix by unmounting it. The kernel maintains a mount stack, so this
reveals what was mounted there before. Introduce cgroup_workdir_mounted
in order to maintain idempotency. Make it thread-local in order to
support test_progs -j.

Pull finegrained timestamp reverts from Christian Brauner:
 "Earlier this week we sent a few minor fixes for the multi-grained
  timestamp work in [1]. While we were polishing those up after Linus
  realized that there might be a nicer way to fix them we received a
  regression report in [2] that fine grained timestamps break gnulib
  tests and thus possibly other tools.

  The kernel will elide fine-grain timestamp updates when no one is
  actively querying for them to avoid performance impacts. So a sequence
  like write(f1) stat(f2) write(f2) stat(f2) write(f1) stat(f1) may
  result in timestamp f1 to be older than the final f2 timestamp even
  though f1 was last written too but the second write didn't update the
  timestamp.

  Such plotholes can lead to subtle bugs when programs compare
  timestamps. For example, the nap() function in [2] will estimate that
  it needs to wait one ns on a fine-grain timestamp enabled filesytem
  between subsequent calls to observe a timestamp change. But in general
  we don't update timestamps with more than one jiffie if we think that
  no one is actively querying for fine-grain timestamps to avoid
  performance impacts.

  While discussing various fixes the decision was to go back to the
  drawing board and ultimately to explore a solution that involves only
  exposing such fine-grained timestamps to nfs internally and never to
  userspace.

  As there are multiple solutions discussed the honest thing to do here
  is not to fix this up or disable it but to cleanly revert. The general
  infrastructure will probably come back but there is no reason to keep
  this code in mainline.

  The general changes to timestamp handling are valid and a good cleanup
  that will stay. The revert is fully bisectable"

vsock/virtio/vhost: MSG_ZEROCOPY preparations

this patchset is first of three parts of another big patchset for
MSG_ZEROCOPY flag support:
https://lore.kernel.org/netdev/20230701063947.3422088-1-AVKrasnov@sberdevices.ru/

During review of this series, Stefano Garzarella <sgarzare@redhat.com>
suggested to split it for three parts to simplify review and merging:

1) virtio and vhost updates (for fragged skbs) <--- this patchset
2) AF_VSOCK updates (allows to enable MSG_ZEROCOPY mode and read
   tx completions) and update for Documentation/.
3) Updates for tests and utils.

This series enables handling of fragged skbs in virtio and vhost parts.
Newly logic won't be triggered, because SO_ZEROCOPY options is still
impossible to enable at this moment (next bunch of patches from big
set above will enable it).

This adds handling of MSG_ZEROCOPY flag on transmission path:

1) If this flag is set and zerocopy transmission is possible (enabled
   in socket options and transport allows zerocopy), then non-linear
   skb will be created and filled with the pages of user's buffer.
   Pages of user's buffer are locked in memory by 'get_user_pages()'.
2) Replaces way of skb owning: instead of 'skb_set_owner_sk_safe()' it
   calls 'skb_set_owner_w()'. Reason of this change is that
   '__zerocopy_sg_from_iter()' increments 'sk_wmem_alloc' of socket, so
   to decrease this field correctly, proper skb destructor is needed:
   'sock_wfree()'. This destructor is set by 'skb_set_owner_w()'.
3) Adds new callback to 'struct virtio_transport': 'can_msgzerocopy'.
   If this callback is set, then transport needs extra check to be able
   to send provided number of buffers in zerocopy mode. Currently, the
   only transport that needs this callback set is virtio, because this
   transport adds new buffers to the virtio queue and we need to check,
   that number of these buffers is less than size of the queue (it is
   required by virtio spec). vhost and loopback transports don't need
   this check.

This is preparation patch for MSG_ZEROCOPY support. It adds handling of
non-linear skbs by replacing direct calls of 'memcpy_to_msg()' with
'skb_copy_datagram_iter()'. Main advantage of the second one is that it
can handle paged part of the skb by using 'kmap()' on each page, but if
there are no pages in the skb, it behaves like simple copying to iov
iterator. This patch also adds new field to the control block of skb -
this value shows current offset in the skb to read next portion of data
(it doesn't matter linear it or not). Idea behind this field is that
'skb_copy_datagram_iter()' handles both types of skb internally - it
just needs an offset from which to copy data from the given skb. This
offset is incremented on each read from skb. This approach allows to
simplify handling of both linear and non-linear skbs, because for
linear skb we need to call 'skb_pull()' after reading data from it,
while in non-linear case we need to update 'data_len'.

netfilter updates for net

The following three patches fix regressions in the netfilter subsystem:

1. Reject attempts to repeatedly toggle the 'dormant' flag in a single
   transaction.  Doing so makes nf_tables lose track of the real state
   vs. the desired state.  This ends with an attempt to unregister hooks
   that were never registered in the first place, which yields a splat.

2. Fix element counting in the new nftables garbage collection infra
   that came with 6.5:  More than 255 expired elements wraps a counter

When users attempt to obtain the coalesce setting using the
ethtool command, current code always returns 0 for tx-usecs.
This is because I225/6 always uses a queue pair setting, hence
tx_coalesce_usecs does not return a value during the
igc_ethtool_get_coalesce() callback process. The pair queue
condition checking in igc_ethtool_get_coalesce() is removed by
this patch so that the user gets information of the value of tx-usecs.

Even if i225/6 is using queue pair setting, there is no harm in
notifying the user of the tx-usecs. The implementation of the current
code may have previously been a copy of the legacy code i210.
Since I225 has the queue pair setting enabled, tx-usecs will always adhere
to the user-set rx-usecs value. An error message will appear when the user
attempts to set the tx-usecs value for the input parameters because,
by default, they should only set the rx-usecs value.

This patch also adds the helper function to get the
previous rx coalesce value similar to tx coalesce.

How to test:
User can get the coalesce value using ethtool command.

Example command:
Get: ethtool -c <interface>

Previous output:

rx-usecs: 3
rx-frames: n/a
rx-usecs-irq: n/a
rx-frames-irq: n/a

tx-usecs: 0
tx-frames: n/a
tx-usecs-irq: n/a

Pull btrfs fixes from David Sterba:
 "A few more followup fixes to the directory listing.

  People have noticed different behaviour compared to other filesystems
  after changes in 6.5. This is now unified to more "logical" and
  expected behaviour while still within POSIX. And a few more fixes for
  stable.

   - change behaviour of readdir()/rewinddir() when new directory
     entries are created after opendir(), properly tracking the last
     entry

   - fix race in readdir when multiple threads can set the last entry
     index for a directory

  Additionally:

   - use exclusive lock when direct io might need to drop privs and call
     notify_change()

   - don't clear uptodate bit on page after an error, this may lead to a
     deadlock in subpage mode

   - fix waiting pattern when multiple readers block on Merkle tree
     data, switch to folios"

  btrfs: fix race between reading a directory and adding entries to it

Pull spi fixes from Mark Brown:
 "A small collection of fixes, plus a new device ID for Intel Granite
  Rapids systems.

  The fix for the i.MX driver is fairly urgent, it's fixing a data
  corruption issue when bits per word isn't 8.

  There's also one fix which was queued but not sent for v6.4 due to
  being minor and arriving at the end of the release"

ASoC: Fixes for v6.6

Quite a large collection of fixes, with numbers boosted by multiple
vendors sending multi-patch serieses.  Nothing super major, and also one
device quirk.
