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.) -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEK2m5VNv+CHkogTfJ8vlZVpUNgaMFAmOWqrMACgkQ8vlZVpUN gaMvmgf+P2C6vzjn13ZdF+GwFTi4fx4TJ5BZT78LQqvTZqhkfk4k1q2SFfHI7nXT ZWdu1KUQ0SYLo64oaSU9W+2B2pmGi/KgUlrwNhy8DFeGStogPuDVfmGWB63p1UQL ld42mE9q7bjY6nCZSKYXPp2jfSwsHuliHBJ4UfzVNAIwjiUEJ7pGeIrMFdLAEkVm TVNzvlUZaHUnVxhpsP6hs+5WNhHQ2IhWz4rwX01ussNgHTijYac4iaL05wpTvF5e 6NtvfmpOEMAbYrmIkJX4RVss4JNsHNOC0E8fjEHlgXJxBiAI6w8GxTxrS52Y4ELH nHXl/pc0L+I8+yh9B9+s0LBaSuPuTg== =lezv -----END PGP SIGNATURE----- Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 updates from Ted Ts'o: "A large number of cleanups and bug fixes, with many of the bug fixes found by Syzbot and fuzzing.
