Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 updates from Ted Ts'o: "This merge window saw the the following new featuers added to ext4: - Direct I/O via iomap (required the iomap-for-next branch from Darrick as a prereq). - Support for using dioread-nolock where the block size < page size. - Support for encryption for file systems where the block size < page size. - Rework of journal credits handling so a revoke-heavy workload will not cause the journal to run out of space. - Replace bit-spinlocks with spinlocks in jbd2 Also included were some bug fixes and cleanups, mostly to clean up corner cases from fuzzed file systems and error path handling" * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (59 commits) ext4: work around deleting a file with i_nlink == 0 safely ext4: add more paranoia checking in ext4_expand_extra_isize handling jbd2: make jbd2_handle_buffer_credits() handle reserved handles ext4: fix a bug in ext4_wait_for_tail_page_commit ext4: bio_alloc with __GFP_DIRECT_RECLAIM never fails ext4: code cleanup for get_next_id ext4: fix leak of quota reservations ext4: remove unused variable warning in parse_options() ext4: Enable encryption for subpage-sized blocks fs/buffer.c: support fscrypt in block_read_full_page() ext4: Add error handling for io_end_vec struct allocation jbd2: Fine tune estimate of necessary descriptor blocks jbd2: Provide trace event for handle restarts ext4: Reserve revoke credits for freed blocks jbd2: Make credit checking more strict jbd2: Rename h_buffer_credits to h_total_credits jbd2: Reserve space for revoke descriptor blocks jbd2: Drop jbd2_space_needed() jbd2: Account descriptor blocks into t_outstanding_credits jbd2: Factor out common parts of stopping and restarting a handle ...
