Subject: [PATCH v2 0/2] f2fs: Fix DIO flags and add ioprio hint

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.

---
Changes in v2:
 - f2fs: Apply bio flags to direct I/O
   - Changed f2fs_io_flags() to accept a direct inode pointer
 - f2fs: use ioprio hint for hot and pinned files
   - Removed an unnecessary f2fs_mark_inode_dirty_sync() call
