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.
