Merge tag 'f2fs-for-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've added two small interfaces: (a) GC_URGENT_LOW
  mode for performance and (b) F2FS_IOC_SEC_TRIM_FILE ioctl for
  security.

  The new GC mode allows Android to run some lower priority GCs in
  background, while new ioctl discards user information without race
  condition when the account is removed.

  In addition, some patches were merged to address latency-related
  issues. We've fixed some compression-related bug fixes as well as edge
  race conditions.

  Enhancements:
   - add GC_URGENT_LOW mode in gc_urgent
   - introduce F2FS_IOC_SEC_TRIM_FILE ioctl
   - bypass racy readahead to improve read latencies
   - shrink node_write lock coverage to avoid long latency

  Bug fixes:
   - fix missing compression flag control, i_size, and mount option
   - fix deadlock between quota writes and checkpoint
   - remove inode eviction path in synchronous path to avoid deadlock
   - fix to wait GCed compressed page writeback
   - fix a kernel panic in f2fs_is_compressed_page
   - check page dirty status before writeback
   - wait page writeback before update in node page write flow
   - fix a race condition between f2fs_write_end_io and f2fs_del_fsync_node_entry

  We've added some minor sanity checks and refactored trivial code
  blocks for better readability and debugging information"
