Pull vfs mount updates from Christian Brauner:
- Mount notifications
The day has come where we finally provide a new api to listen for
mount topology changes outside of /proc/<pid>/mountinfo. A mount
namespace file descriptor can be supplied and registered with
fanotify to listen for mount topology changes.
Currently notifications for mount, umount and moving mounts are
generated. The generated notification record contains the unique
mount id of the mount.
The listmount() and statmount() api can be used to query detailed
information about the mount using the received unique mount id.
This allows userspace to figure out exactly how the mount topology
changed without having to generating diffs of /proc/<pid>/mountinfo
in userspace.
- Support O_PATH file descriptors with FSCONFIG_SET_FD in the new mount
api
- Support detached mounts in overlayfs
Since last cycle we support specifying overlayfs layers via file
descriptors. However, we don't allow detached mounts which means
userspace cannot user file descriptors received via
open_tree(OPEN_TREE_CLONE) and fsmount() directly. They have to
attach them to a mount namespace via move_mount() first.
This is cumbersome and means they have to undo mounts via umount().
Allow them to directly use detached mounts.
- Allow to retrieve idmappings with statmount
Currently it isn't possible to figure out what idmapping has been
attached to an idmapped mount. Add an extension to statmount() which
allows to read the idmapping from the mount.
- Allow creating idmapped mounts from mounts that are already idmapped
So far it isn't possible to allow the creation of idmapped mounts
from already idmapped mounts as this has significant lifetime
implications. Make the creation of idmapped mounts atomic by allow to
pass struct mount_attr together with the open_tree_attr() system call
allowing to solve these issues without complicating VFS lookup in any
way.
The system call has in general the benefit that creating a detached
mount and applying mount attributes to it becomes an atomic operation
for userspace.
- Add a way to query statmount() for supported options
Allow userspace to query which mount information can be retrieved
through statmount().
- Allow superblock owners to force unmount

There is an unnecessary NULL check of cifs_sb in smb2_is_path_accessible(),
since cifs_sb is dereferenced multiple times prior to it.
It seems that there is no need to introduce any NULL checks of cifs_sb,
since arguments of smb2_is_path_accessible() are assumed to be non-NULL.
Therefore, this redundant check can be removed.

There is an unnecessary NULL check of inode in cifs_oplock_break(), since
there are multiple dereferences of cinode prior to it.
Based on usage of cifs_oplock_break() in cifs_new_fileinfo() we can safely
assume that inode is not NULL, so there is no need to check inode in
cifs_oplock_break() at all.
Therefore, this redundant check can be removed.

For multichannel mounts, when a new channel is successfully opened
we currently log 'successfully opened new channel on iface: <>' as
cifs_dbg(VFS..) which is eventually translated into a pr_err log.
Marking these informational logs as error logs may lead to confusion
for users so they will now be logged as info logs instead.

We're hitting some issues with uninitialized struct padding, flagged by
kmsan.
They appear to be falso positives, otherwise bch2_accounting_validate()
would have flagged them as "junk at end". But for now, we'll need to
initialize disk_accounting_pos with memset().
This adds a new helper, bch2_disk_accounting_mod2(), that initializes a
disk_accounting_pos and does the accounting mod all at once - so overall
things actually get slightly more ergonomic.
BCH_DISK_ACCOUNTING_replicas keys are left for now; KMSAN isn't warning
about them and they're a bit special.

More on the "full online self healing" project:
We now run most of the dirent <-> inode consistency checks, with repair
code, at runtime - the exact same check and repair code that fsck runs.

Prep work for calling bch2_check_dirent_target() from bch2_lookup().
- Add an inline wrapper, if the target and backpointer match we can skip
the function call.
- We don't (yet?) want to remove the dirent we did the lookup from (when
we find a directory or subvol with multiple valid dirents pointing to
it), we can defer on that until later. For now, add an "are we in
fsck?" parameter.

The offset_into_extent bit was copied from the read path, but it's
unnecessary here, where we always want to read and move the entire
indirect extent, and it causes the assertion pop - because we're using a
non-extents iterator, which always points to the end of the reflink
pointer.

Just use sha256() instead of the clunky crypto API. This is much
simpler.

Since bcachefs does not access crc32c and crc64 through the crypto API,
there is no need to use module softdeps to ensure they are loaded.
