The following series is for continued discussion of the need for
and implementation of stable directory offsets for shmemfs/tmpfs.
As discussed in Vancouver, I've re-implemented this change in libfs
so that other "simple" filesystems can use it. There were a few
other suggestions made during that event that I haven't tried yet.
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
