Merge tag 'f2fs-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "In this round, we've added some knobs to enhance compression feature and harden testing environment. In addition, we've fixed several bugs reported from Android devices such as long discarding latency, device hanging during quota_sync, etc. Enhancements: - support lzo-rle algorithm - add two ioctls to release and reserve blocks for compression - support partial truncation/fiemap on compressed file - introduce sysfs entries to attach IO flags explicitly - add iostat trace point along with read io stat Bug fixes: - fix long discard latency - flush quota data by f2fs_quota_sync correctly - fix to recover parent inode number for power-cut recovery - fix lz4/zstd output buffer budget - parse checkpoint mount option correctly - avoid inifinite loop to wait for flushing node/meta pages - manage discard space correctly And some refactoring and clean up patches were added" * tag 'f2fs-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (51 commits) f2fs: attach IO flags to the missing cases f2fs: add node_io_flag for bio flags likewise data_io_flag f2fs: remove unused parameter of f2fs_put_rpages_mapping() f2fs: handle readonly filesystem in f2fs_ioc_shutdown() f2fs: avoid utf8_strncasecmp() with unstable name f2fs: don't return vmalloc() memory from f2fs_kmalloc() f2fs: fix retry logic in f2fs_write_cache_pages() f2fs: fix wrong discard space f2fs: compress: don't compress any datas after cp stop f2fs: remove unneeded return value of __insert_discard_tree() f2fs: fix wrong value of tracepoint parameter f2fs: protect new segment allocation in expand_inode_data f2fs: code cleanup by removing ifdef macro surrounding f2fs: avoid inifinite loop to wait for flushing node pages at cp_error f2fs: flush dirty meta pages when flushing them f2fs: fix checkpoint=disable:%u%% f2fs: compress: fix zstd data corruption f2fs: add compressed/gc data read IO stat f2fs: fix potential use-after-free issue f2fs: compress: don't handle non-compressed data in workqueue ...
