Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 updates from Ted Ts'o: "Mostly performance and bug fixes, plus some cleanups. The one new feature this merge window is a new ioctl EXT4_IOC_SWAP_BOOT which allows installation of a hidden inode designed for boot loaders." * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (50 commits) ext4: fix type-widening bug in inode table readahead code ext4: add check for inodes_count overflow in new resize ioctl ext4: fix Kconfig documentation for CONFIG_EXT4_DEBUG ext4: fix online resizing for ext3-compat file systems jbd2: trace when lock_buffer in do_get_write_access takes a long time ext4: mark metadata blocks using bh flags buffer: add BH_Prio and BH_Meta flags ext4: mark all metadata I/O with REQ_META ext4: fix readdir error in case inline_data+^dir_index. ext4: fix readdir error in the case of inline_data+dir_index jbd2: use kmem_cache_zalloc instead of kmem_cache_alloc/memset ext4: mext_insert_extents should update extent block checksum ext4: move quota initialization out of inode allocation transaction ext4: reserve xattr index for Rich ACL support jbd2: reduce journal_head size ext4: clear buffer_uninit flag when submitting IO ext4: use io_end for multiple bios ext4: make ext4_bio_write_page() use BH_Async_Write flags ext4: Use kstrtoul() instead of parse_strtoul() ext4: defragmentation code cleanup ...
