Pull ext4 updates from Ted Ts'o: - add GETFSMAP support - some performance improvements for very large file systems and for random write workloads into a preallocated file - bug fixes and cleanups. * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: jbd2: cleanup write flags handling from jbd2_write_superblock() ext4: mark superblock writes synchronous for nobarrier mounts ext4: inherit encryption xattr before other xattrs ext4: replace BUG_ON with WARN_ONCE in ext4_end_bio() ext4: avoid unnecessary transaction stalls during writeback ext4: preload block group descriptors ext4: make ext4_shutdown() static ext4: support GETFSMAP ioctls vfs: add common GETFSMAP ioctl definitions ext4: evict inline data when writing to memory map ext4: remove ext4_xattr_check_entry() ext4: rename ext4_xattr_check_names() to ext4_xattr_check_entries() ext4: merge ext4_xattr_list() into ext4_listxattr() ext4: constify static data that is never modified ext4: trim return value and 'dir' argument from ext4_insert_dentry() jbd2: fix dbench4 performance regression for 'nobarrier' mounts jbd2: Fix lockdep splat with generic/270 test mm: retry writepages() on ENOMEM when doing an data integrity writeback
