f2fs: do not allow partial truncation on pinned file (2022-01-10 09:05:09 -0800)
----------------------------------------------------------------
f2fs-for-5.17-rc1
In this round, we've tried to address some performance issues in f2fs_checkpoint
and direct IO flows. Also, there was a work to enhance the page cache management
used for compression. Other than them, we've done typical work including sysfs,
code clean-ups, tracepoint, sanity check, in addition to bug fixes on corner
cases.
Enhancement:
- use iomap for direct IO
- try to avoid lock contention to improve f2fs_ckpt speed
- avoid unnecessary memory allocation in compression flow
- POSIX_FADV_DONTNEED drops the page cache containing compression pages
- add some sysfs entries (gc_urgent_high_remaining, pending_discard)
Bug fix:
- try not to expose unwritten blocks to user by DIO
: this was added to avoid merge conflict; another patch is coming to address
other missing case.
- relax minor error condition for file pinning feature used in Android OTA
- fix potential deadlock case in compression flow
- should not truncate any block on pinned file
In addition, we've done some code clean-ups and tracepoint/sanity check
improvement.
