Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 updates from Ted Ts'o: "All cleanups and bug fixes; most notably, fix some problems discovered in ext4's NFS support, and fix an ioctl (EXT4_IOC_GROUP_ADD) used by old versions of e2fsprogs which we accidentally broke a while back. Also fixed some error paths in ext4's quota and inline data support. Finally, improve tail latency in jbd2's commit code" * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: ext4: check for shutdown and r/o file system in ext4_write_inode() ext4: force inode writes when nfsd calls commit_metadata() ext4: avoid declaring fs inconsistent due to invalid file handles ext4: include terminating u32 in size of xattr entries when expanding inodes ext4: compare old and new mode before setting update_mode flag ext4: fix EXT4_IOC_GROUP_ADD ioctl ext4: hard fail dax mount on unsupported devices jbd2: update locking documentation for transaction_t ext4: remove redundant condition check jbd2: clean up indentation issue, replace spaces with tab ext4: clean up indentation issues, remove extraneous tabs ext4: missing unlock/put_page() in ext4_try_to_write_inline_data() ext4: fix possible use after free in ext4_quota_enable jbd2: avoid long hold times of j_state_lock while committing a transaction ext4: add ext4_sb_bread() to disambiguate ENOMEM cases
