When we're discarding old btree blocks after a repair, only invalidate
the buffers for the ones that we're freeing -- if the metadata was
crosslinked with another data structure, we don't want to touch it.

Reaping blocks after a repair is a complicated affair involving a lot of
rmap btree lookups and figuring out if we're going to unmap or free old
metadata blocks that might be crosslinked.  Eventually, we will need to
be able to reap per-AG metadata blocks, bmbt blocks from inode forks,
garbage CoW staging extents, and (even later) blocks from btrees rooted
in inodes.  This results in a lot of reaping code, so we might as well
split that off while it's easy.

These two functions date from the era when I thought that we could

I nominate Chandan Babu to take over release management for the upstream
kernel's XFS code.  He has had sufficient experience merging backports
to the 5.4 LTS tree, testing them, and sending them on to the LTS leads.

NOTE: I am /not/ nominating Chandan to take on any of the other roles I
have just dropped.  Bug triager, testing lead, and community manager are
open positions that need to be filled.  There's also maintainer for
supported LTS releases (4.14, 4.19, 5.10...).

I burned out years ago trying to juggle the roles senior developer,
reviewer, tester, triager (crappily), release manager, and (at times)
manager liaison.  There's enough work here in this one subsystem for a
team of 20 FT, but instead we're squeezed to half that.  I thought if I
could hold on just a bit longer I could help to maintain the focus on
long term development to improve the experience for users.  I was wrong.

Nowadays, people working on XFS seem to spend most of their time on
distro kernel backports and dealing with AI-generated corner case bug
reports that aren't user reports.  Reviewing has become a nightmare of
sifting through under-documented kernel code trying to decide if this
new feature won't break all the other features.  Getting reviews is an
unpleasant process of negotiating with demands for further cleanups,
trying to figure out if a review comment is based in experience or
unfamiliarity, and wondering if the silence means anything.

For now, I will continue to review patches and will try to get online

Pull vfs fixes from Christian Brauner:

  fs: rely on ->iterate_shared to determine f_pos locking
  vfs: get rid of old '->iterate' directory operation

  open: make RESOLVE_CACHED correctly test for O_TMPFILE

Now that we removed ->iterate we don't need to check for either
->iterate or ->iterate_shared in file_needs_f_pos_lock(). Simply check
for ->iterate_shared instead. This will tell us whether we need to
unconditionally take the lock. Not just does it allow us to avoid
checking f_inode's mode it also actually clearly shows that we're
locking because of readdir.
Signed-off-by: Christian Brauner <brauner@kernel.org>

All users now just use '->iterate_shared()', which only takes the
directory inode lock for reading.

Filesystems that never got convered to shared mode now instead use a
wrapper that drops the lock, re-takes it in write mode, calls the old
function, and then downgrades the lock back to read mode.

This way the VFS layer and other callers no longer need to care about
filesystems that never got converted to the modern era.

The filesystems that use the new wrapper are ceph, coda, exfat, jfs,
ntfs, ocfs2, overlayfs, and vboxsf.

Honestly, several of them look like they really could just iterate their
directories in shared mode and skip the wrapper entirely, but the point
of this change is to not change semantics or fix filesystems that
haven't been fixed in the last 7+ years, but to finally get rid of the
dual iterators.

I'm looking at the directory handling due to the discussion about f_pos
locking (see commit 79796425: "file: reinstate f_pos locking
optimization for regular files"), and wanting to clean that up.

And one source of ugliness is how we were supposed to move filesystems
over to the '->iterate_shared()' function that only takes the inode lock
for reading many many years ago, but several filesystems still use the
bad old '->iterate()' that takes the inode lock for exclusive access.

See commit 61922694 ("introduce a parallel variant of ->iterate()")
that also added some documentation stating

      Old method is only used if the new one is absent; eventually it will
      be removed.  Switch while you still can; the old one won't stay.

and that was back in April 2016.  Here we are, many years later, and the
old version is still clearly sadly alive and well.

Now, some of those old style iterators are probably just because the
filesystem may end up having per-inode mutable data that it uses for
iterating a directory, but at least one case is just a mistake.

Al switched over most filesystems to use '->iterate_shared()' back when
it was introduced.  In particular, the /proc filesystem was converted as
one of the first ones in commit f50752ea ("switch all procfs
directories ->iterate_shared()").

But then later one new user of '->iterate()' was then re-introduced by
commit 6d9c939d ("procfs: add smack subdir to attrs").

And that's clearly not what we wanted, since that new case just uses the
same 'proc_pident_readdir()' and 'proc_pident_lookup()' helper functions
that other /proc pident directories use, and they are most definitely
safe to use with the inode lock held shared.

So just fix it.

This still leaves a fair number of oddball filesystems using the
old-style directory iterator (ceph, coda, exfat, jfs, ntfs, ocfs2,
overlayfs, and vboxsf), but at least we don't have any remaining in the
core filesystems.

I'm going to add a wrapper function that just drops the read-lock and
takes it as a write lock, so that we can clean up the core vfs layer and
make all the ugly 'this filesystem needs exclusive inode locking' be
just filesystem-internal warts.

I just didn't want to make that conversion when we still had a core user
left.

In commit 20ea1e7d ("file: always lock position for
FMODE_ATOMIC_POS") we ended up always taking the file pos lock, because
pidfd_getfd() could get a reference to the file even when it didn't have
an elevated file count due to threading of other sharing cases.

But Mateusz Guzik reports that the extra locking is actually measurable,
so let's re-introduce the optimization, and only force the locking for
directory traversal.

Directories need the lock for correctness reasons, while regular files
only need it for "POSIX semantics".  Since pidfd_getfd() is about
debuggers etc special things that are _way_ outside of POSIX, we can
relax the rules for that case.

Systems which implement SME without also implementing SVE are
architecturally valid but were not initially supported by the kernel,
unfortunately we missed one issue in the ptrace code.

The SVE register setting code is shared between SVE and streaming mode
SVE. When we set full SVE register state we currently enable TIF_SVE
unconditionally, in the case where streaming SVE is being configured on a
system that supports vanilla SVE this is not an issue since we always
initialise enough state for both vector lengths but on a system which only
support SME it will result in us attempting to restore the SVE vector
length after having set streaming SVE registers.

Fix this by making the enabling of SVE conditional on setting SVE vector
state. If we set streaming SVE state and SVE was not already enabled this
will result in a SVE access trap on next use of normal SVE, this will cause
us to flush our register state but this is fine since the only way to
trigger a SVE access trap would be to exit streaming mode which will cause
the in register state to be flushed anyway.

Currently the rust allocator simply passes the size of the type Layout
to krealloc(), and in theory the alignment requirement from the type
Layout may be larger than the guarantee provided by SLAB, which means
the allocated object is mis-aligned.

Fix this by adjusting the allocation size to the nearest power of two,
which SLAB always guarantees a size-aligned allocation. And because Rust
guarantees that the original size must be a multiple of alignment and
the alignment must be a power of two, then the alignment requirement is
satisfied.

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bpf and wireless.

  Nothing scary here. Feels like the first wave of regressions from v6.5
  is addressed - one outstanding fix still to come in TLS for the
  sendpage rework.

  Current release - regressions:

   - udp: fix __ip_append_data()'s handling of MSG_SPLICE_PAGES

   - dsa: fix older DSA drivers using phylink

  Previous releases - regressions:

   - gro: fix misuse of CB in udp socket lookup

   - mlx5: unregister devlink params in case interface is down

   - Revert "wifi: ath11k: Enable threaded NAPI"

  Previous releases - always broken:

   - sched: cls_u32: fix match key mis-addressing

   - sched: bind logic fixes for cls_fw, cls_u32 and cls_route

   - add bound checks to a number of places which hand-parse netlink

   - bpf: disable preemption in perf_event_output helpers code

   - qed: fix scheduling in a tasklet while getting stats

   - avoid using APIs which are not hardirq-safe in couple of drivers,
     when we may be in a hard IRQ (netconsole)

   - wifi: cfg80211: fix return value in scan logic, avoid page
     allocator warning

   - wifi: mt76: mt7615: do not advertise 5 GHz on first PHY of MT7615D
     (DBDC)

  Misc:

   - drop handful of inactive maintainers, put some new in place"

Willem and Jason have agreed to take over the maintainer
duties for TUN/TAP, thank you!

There's an existing entry for TUN/TAP which only covers
the user mode Linux implementation.
Since we haven't heard from Maxim on the list for almost
a decade, extend that entry and take it over, rather than
adding a new one.

wireless fixes for v6.5

We did some house cleaning in MAINTAINERS file so several patches
about that. Few regressions fixed and also fix some recently enabled
memcpy() warnings. Only small commits and nothing special standing
out.
