ext4: fix reserved cluster accounting in __es_remove_extent() (2022-12-09 00:58:04 -0500)
----------------------------------------------------------------
A large number of cleanups and bug fixes, with many of the bug fixes
found by Syzbot and fuzzing. (Many of the bug fixes involve less-used
ext4 features such as fast_commit, inline_data and bigalloc.)
In addition, remove the writepage function for ext4, since the
medium-term plan is to remove ->writepage() entirely. (The VM doesn't
need or want writepage() for writeback, since it is fine with
->writepages() so long as ->migrate_folio() is implemented.)
