Pull vfs fixes from Christian Brauner:
- For some reason we went from zero to three maintainers for HFS/HFS+
in a matter of days. The lesson to learn from this might just be that
we need to threaten code removal more often!?
- Fix a regression introduced by enabling large folios for lage logical
block sizes. This has caused issues for noref migration with large
folios due to sleeping while in an atomic context.
New sleeping variants of pagecache lookup helpers are introduced.
These helpers take the folio lock instead of the mapping's private
spinlock. The problematic users are converted to the sleeping
variants and serialize against noref migration. Atomic users will
bail on seeing the new BH_Migrate flag.
This also shrinks the critical region of the mapping's private lock
and the new blocking callers reduce contention on the spinlock for
bdev mappings.
- Fix two bugs in do_move_mount() when with MOVE_MOUNT_BENEATH. The
first bug is using a mountpoint that is located on a mount we're not
holding a reference to. The second bug is putting the mountpoint
after we've called namespace_unlock() as it's no longer guaranteed
that it does stay a mountpoint.
- Remove a pointless call to vfs_getattr_nosec() in the devtmpfs code
just to query i_mode instead of simply querying the inode directly.
This also avoids lifetime issues for the dm code by an earlier bugfix
this cycle that moved bdev_statx() handling into vfs_getattr_nosec().
- Fix AT_FDCWD handling with getname_maybe_null() in the xattr code.
- Fix a performance regression for files when multiple callers issue a
close when it's not the last reference.
- Remove a duplicate noinline annotation from pipe_clear_nowait().

Brandon Kammerdiener says:
====================
This patchset fixes an endless loop condition that can occur in
bpf_for_each_hash_elem, causing the core to softlock. My understanding is
that a combination of RCU list deletion and insertion introduces the new
element after the iteration cursor and that there is a chance that an RCU
reader may in fact use this new element in iteration. The patch uses a
_safe variant of the macro which gets the next element to iterate before
executing the loop body for the current element.
I have also added a subtest in the for_each selftest that can trigger this
condition without the fix.
Changes since v2:
- Renaming and additional checks in selftests/bpf/prog_tests/for_each.c
Changes since v1:
- Added missing Signed-off-by lines to both patches

The recent move of the bdev_statx call to the low-level vfs_getattr_nosec
helper caused it being used by devtmpfs, which leads to deadlocks in
md teardown due to the block device lookup and put interfering with the
unusual lifetime rules in md.
But as handle_remove only works on inodes created and owned by devtmpfs
itself there is no need to use vfs_getattr_nosec vs simply reading the
mode from the inode directly. Switch to that to avoid the bdev lookup
or any other unintentional side effect.

Restart handling in the previous patch was incorrect, so: move btree
operations into a separate helper, and run it with a lockrestart_do().
Additionally, clarify whether pagecache or the btree takes precedence.
Right now, the btree takes precedence: this is incorrect, but it's
needed to pass fstests. Add a giant comment explaining why.

bcachefs currently populates fiemap data from the extents btree.
This works correctly when the fiemap sync flag is provided, but if
not, it skips all delalloc extents that have not yet been flushed.
This is because delalloc extents from buffered writes are first
stored as reservation in the pagecache, and only become resident in
the extents btree after writeback completes.
Update the fiemap implementation to process holes between extents by
scanning pagecache for data, via seek data/hole. If a valid data
range is found over a hole in the extent btree, fake up an extent
key and flag the extent as delalloc for reporting to userspace.
Note that this does not necessarily change behavior for the case
where there is dirty pagecache over already written extents, where
when in COW mode, writeback will allocate new blocks for the
underlying ranges. The existing behavior is consistent with btrfs
and it is recommended to use the sync flag for the most up to date
extent state from fiemap.

The bulk of the loop in bch2_fiemap() involves processing the
current extent key from the iter, including following indirections
and trimming the extent size and such. This patch makes a few
changes to reduce the size of the loop and facilitate future changes
to support delalloc extents.
Define a new bch_fiemap_extent structure to wrap the bkey buffer
that holds the extent key to report to userspace along with
associated fiemap flags. Update bch2_fill_extent() to take the
bch_fiemap_extent as a param instead of the individual fields.
Finally, lift the bulk of the extent processing into a
bch2_fiemap_extent() helper that takes the current key and formats
the bch_fiemap_extent appropriately for the fill function.
No functional changes intended by this patch.

FIEMAP_FLAG_SYNC handling was deliberately moved into core code in
commit 45dd052e67 ("fs: handle FIEMAP_FLAG_SYNC in fiemap_prep"),
released in kernel v5.8. Update bcachefs accordingly.

At the end of the inode, on an extents iterator, peek_slot() has to
advance to the next position to avoid returning a 0 size extent, which
is not allowed.
Changing iter->pos confuses peek_prev(), but we don't need to call
peek_slot() in this case.

The issue this assert is guarding against is that in
BTREE_ITER_filter_snapshots mode we only want to be iterating within a
single inode number - if we iterate into another inode number with keys
for a different snapshot tree, we'll loop arbitrarily long before
finding a key we can return.
This comes up in the unit tests, where we're using inode 0 for our test
keys.

If we aren't mounting with the correct degraded option, it's helpful to
know that before we fail to mount degraded.

casefolding results in additional aliases on lookup for the
non-casefolded names - these need invalidating on unlink.
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
Add casefolding to bch2_lookup_trans:
During the delay between when casefolding was written and when it was
merged, the main filesystem lookup path grew self healing - which meant
it was no longer using bch2_dirent_lookup_trans(), where casefolding on
lookups happens.

The XOL (execute out-of-line) buffer is used to single-step the
replaced instruction(s) for uprobes. The RISC-V port was missing a
proper fence.i (i$ flushing) after constructing the XOL buffer, which
can result in incorrect execution of stale/broken instructions.
This was found running the BPF selftests "test_progs:
uprobe_autoattach, attach_probe" on the Spacemit K1/X60, where the
uprobes tests randomly blew up.

The flush_icache_range() function is implemented as a "function-like
macro with unused parameters", which can result in "unused variables"
warnings.
Replace the macro with a static inline function, as advised by
Documentation/process/coding-style.rst.
