[PATCH v4 0/3] shmemfs stable directory offsets

[Chuck Lever <cel@kernel.org>]

The following series is for continued discussion of the need for
and implementation of stable directory offsets for shmemfs/tmpfs.


Changes since v3:
- Rebased on v6.4
- Fixed error handling bugs

Changes since v2:
- Move bulk of stable offset support into fs/libfs.c
- Replace xa_find_after with xas_find_next for efficiency

Changes since v1:
- Break the single patch up into a series

Changes since RFC:
- Destroy xarray in shmem_destroy_inode() instead of free_in_core_inode()
- A few cosmetic updates
