Hey Linus,
/* Summary */
This contains some minor work for the iomap subsystem:
- Add documentaiton on the design of iomap and how to port to it.
- Optimize iomap_read_folio().
- Bring back the change to iomap_write_end() to no increase i_size. This is
accompanied by a change to xfs to reserve blocks for truncating large
realtime inodes to avoid exposing stale data when iomap_write_end()
stops increasing i_size.
/* Testing */
clang: Debian clang version 16.0.6 (26)
gcc: (Debian 13.2.0-24)
All patches are based on v6.10-rc4 and have been sitting in linux-next.
No build failures or warnings were observed.
/* Conflicts */
No known conflicts.
