[PATCH 0/2] f2fs: Fix DIO flags and add ioprio hint

Posted by Daniel Lee 4 months ago

The first patch corrects an issue where Direct I/O (DIO) writes ignore
bio flag hints (e.g., F2FS_IOPRIO_WRITE for REQ_PRIO),
making them inconsistent with buffered I/O.

The second patch is to set an I/O priority hint for hot files on creation
and pinned files by default.

Daniel Lee (2):
  f2fs: Apply bio flags to direct I/O
  f2fs: use ioprio hint for hot and pinned files
