[0/7] fs: fix inode->i_flctx accesses

Message

Jeff Layton Nov. 16, 2022, 3:17 p.m. UTC

The inode->i_flctx field is set via a cmpxchg operation, which is a
release op. This means that most callers need to use an acquire to
access it.

This series adds a new helper function for that, and replaces the
existing accesses of i_flctx with that. The later patches then convert
the various subsystems that access i_flctx directly to use the new
helper.

Assuming there are no objectsions, I'll plan to merge this for v6.2 via
my tree. If any maintainers want to take the subsystem patches in via
their trees, let me know and we'll work it out.
