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"
