In this cycle, metadata compression is now supported due to user requests [1]. It can be useful for embedded use cases or archiving a large number of small files. Additionally, readdir performance has been improved by enabling readahead (note that it was already common practice for ext3/4 non-dx and f2fs directories). We may consider further improvements later to align with ext4's s_inode_readahead_blks behavior for slow devices too. The remaining commits are minor. All commits have been in -next and no potential merge conflict is observed.
