Merge tag 'f2fs-for-v5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "Another round of various bug fixes came in. Damien improved SMR drive
  support a bit, and Chao replaced BUG_ON() with reporting errors to
  user since we've not hit from users but did hit from crafted images.
  We've found a disk layout bug in large_nat_bits feature which supports
  very large NAT entries enabled at mkfs. If the feature is enabled, it
  will give a notice to run fsck to correct the on-disk layout.

  Enhancements:
   - reduce memory consumption for SMR drive
   - better discard handling for multiple partitions
   - tracepoints for f2fs_file_write_iter/f2fs_filemap_fault
   - allow to change CP_CHKSUM_OFFSET
   - detect wrong layout of large_nat_bitmap feature
   - enhance checking valid data indices

  Bug fixes:
   - Multiple partition support for SMR drive
   - deadlock problem in f2fs_balance_fs_bg
   - add boundary checks to fix abnormal behaviors on fuzzed images
   - inline_xattr space calculations
   - replace f2fs_bug_on with errors

  In addition, this series contains various memory boundary check and
  sanity check of on-disk consistency"
