Changes since v5:
- Improve error flow in simple_offset_add()

This series (against v6.13-rc3) has been pushed to:

https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git/log/?h=tmpfs-fixes

Chuck Lever (5):
  libfs: Return ENOSPC when the directory offset range is exhausted
  Revert "libfs: Add simple_offset_empty()"
  Revert "libfs: fix infinite directory reads for offset dir"
  libfs: Replace simple_offset end-of-directory detection
  libfs: Use d_children list to iterate simple_offset directories

Applied to the vfs-6.14.misc branch of the vfs/vfs.git tree.
Patches in the vfs-6.14.misc branch should appear in linux-next soon.

Please report any outstanding bugs that were missed during review in a
new review to the original patch series allowing us to drop it.

It's encouraged to provide Acked-bys and Reviewed-bys even though the
patch has now been applied. If possible patch trailers will be updated.

Note that commit hashes shown below are subject to change due to rebase,
trailer updates or similar. If in doubt, please check the listed branch.
