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.
Enhancement:
- 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 fix:
- 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.
