Merge tag 'for-f2fs-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "In this round, we've focused on enhancing performance with regards to block allocation, GC, and discard/in-place-update IO controls. There are a bunch of clean-ups as well as minor bug fixes. Enhancements: - disable heap-based allocation by default - issue small-sized discard commands by default - change the policy of data hotness for logging - distinguish IOs in terms of size and wbc type - start SSR earlier to avoid foreground GC - enhance data structures managing discard commands - enhance in-place update flow - add some more fault injection routines - secure one more xattr entry Bug fixes: - calculate victim cost for GC correctly - remain correct victim segment number for GC - race condition in nid allocator and initializer - stale pointer produced by atomic_writes - fix missing REQ_SYNC for flush commands - handle missing errors in more corner cases" * tag 'for-f2fs-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (111 commits) f2fs: fix a mount fail for wrong next_scan_nid f2fs: enhance scalability of trace macro f2fs: relocate inode_{,un}lock in F2FS_IOC_SETFLAGS f2fs: Make flush bios explicitely sync f2fs: show available_nids in f2fs/status f2fs: flush dirty nats periodically f2fs: introduce CP_TRIMMED_FLAG to avoid unneeded discard f2fs: allow cpc->reason to indicate more than one reason f2fs: release cp and dnode lock before IPU f2fs: shrink size of struct discard_cmd f2fs: don't hold cmd_lock during waiting discard command f2fs: nullify fio->encrypted_page for each writes f2fs: sanity check segment count f2fs: introduce valid_ipu_blkaddr to clean up f2fs: lookup extent cache first under IPU scenario f2fs: reconstruct code to write a data page f2fs: introduce __wait_discard_cmd f2fs: introduce __issue_discard_cmd f2fs: enable small discard by default f2fs: delay awaking discard thread ...
