The following series implements stable directory offsets for
shmemfs/tmpfs and provides infrastructure for use by other file
systems that are based on simplefs.
Changes since v5:
- Rename functions and structures
Changes since v4:
- Remove new fields from struct inode/dentry
- Remove EXPORT_SYMBOL and extern for new functions
- Try again to fix error handling for rename_exchange
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
