Pull f2fs updates from Jaegeuk Kim: "In this round, we've mainly focused on fixing bugs and addressing issues in recently introduced compression support. Enhancement: - add zstd support, and set LZ4 by default - add ioctl() to show # of compressed blocks - show mount time in debugfs - replace rwsem with spinlock - avoid lock contention in DIO reads Some major bug fixes wrt compression: - compressed block count - memory access and leak - remove obsolete fields - flag controls Other bug fixes and clean ups: - fix overflow when handling .flags in inode_info - fix SPO issue during resize FS flow - fix compression with fsverity enabled - potential deadlock when writing compressed pages - show missing mount options" * tag 'f2fs-for-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (66 commits) f2fs: keep inline_data when compression conversion f2fs: fix to disable compression on directory f2fs: add missing CONFIG_F2FS_FS_COMPRESSION f2fs: switch discard_policy.timeout to bool type f2fs: fix to verify tpage before releasing in f2fs_free_dic() f2fs: show compression in statx f2fs: clean up dic->tpages assignment f2fs: compress: support zstd compress algorithm f2fs: compress: add .{init,destroy}_decompress_ctx callback f2fs: compress: fix to call missing destroy_compress_ctx() f2fs: change default compression algorithm f2fs: clean up {cic,dic}.ref handling f2fs: fix to use f2fs_readpage_limit() in f2fs_read_multi_pages() f2fs: xattr.h: Make stub helpers inline f2fs: fix to avoid double unlock f2fs: fix potential .flags overflow on 32bit architecture f2fs: fix NULL pointer dereference in f2fs_verity_work() f2fs: fix to clear PG_error if fsverity failed f2fs: don't call fscrypt_get_encryption_info() explicitly in f2fs_tmpfile() f2fs: don't trigger data flush in foreground operation ...

f2fs: keep inline_data when compression conversion

f2fs: wire up FS_IOC_GET_ENCRYPTION_NONCE

2020-03-20T04:57:06Z

This new ioctl retrieves a file's encryption nonce, which is useful for testing. See the corresponding fs/crypto/ patch for more details. Link: https://lore.kernel.org/r/20200314205052.93294-4-ebiggers@kernel.org Signed-off-by: Eric Biggers

f2fs: clean up lfs/adaptive mount option

2020-03-19T18:41:25Z

This patch removes F2FS_MOUNT_ADAPTIVE and F2FS_MOUNT_LFS mount options, and add F2FS_OPTION.fs_mode with below two status to indicate filesystem mode. enum { FS_MODE_ADAPTIVE, /* use both lfs/ssr allocation */ FS_MODE_LFS, /* use lfs allocation only */ }; It can enhance code readability and fs mode's scalability.

f2fs: allow to clear F2FS_COMPR_FL flag

2020-03-11T15:25:38Z

If regular inode has no compressed cluster, allow using 'chattr -c' to remove its compress flag, recovering it to a non-compressed file. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim
