Merge tag 'for-f2fs-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "This round introduces several interesting features such as on-disk NAT bitmaps, IO alignment, and a discard thread. And it includes a couple of major bug fixes as below. Enhancements: - introduce on-disk bitmaps to avoid scanning NAT blocks when getting free nids - support IO alignment to prepare open-channel SSD integration in future - introduce a discard thread to avoid long latency during checkpoint and fstrim - use SSR for warm node and enable inline_xattr by default - introduce in-memory bitmaps to check FS consistency for debugging - improve write_begin by avoiding needless read IO Bug fixes: - fix broken zone_reset behavior for SMR drive - fix wrong victim selection policy during GC - fix missing behavior when preparing discard commands - fix bugs in atomic write support and fiemap - workaround to handle multiple f2fs_add_link calls having same name ... and it includes a bunch of clean-up patches as well" * tag 'for-f2fs-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (97 commits) f2fs: avoid to flush nat journal entries f2fs: avoid to issue redundant discard commands f2fs: fix a plint compile warning f2fs: add f2fs_drop_inode tracepoint f2fs: Fix zoned block device support f2fs: remove redundant set_page_dirty() f2fs: fix to enlarge size of write_io_dummy mempool f2fs: fix memory leak of write_io_dummy mempool during umount f2fs: fix to update F2FS_{CP_}WB_DATA count correctly f2fs: use MAX_FREE_NIDS for the free nids target f2fs: introduce free nid bitmap f2fs: new helper cur_cp_crc() getting crc in f2fs_checkpoint f2fs: update the comment of default nr_pages to skipping f2fs: drop the duplicate pval in f2fs_getxattr f2fs: Don't update the xattr data that same as the exist f2fs: kill __is_extent_same f2fs: avoid bggc->fggc when enough free segments are avaliable after cp f2fs: select target segment with closer temperature in SSR mode f2fs: show simple call stack in fault injection message f2fs: no need lock_op in f2fs_write_inline_data ...
