This series adds directory-listing support to the ext4l filesystem
driver. It exports a few required functions from the Linux ext4 code,
fixes the dir_emit() stub to properly call the actor callback, and
implements ext4l_ls() with path resolution and symlink following.


Simon Glass (12):
  ext4l: Fix format warning in mballoc.c
  fs: ext4l: Mount filesystems read-write
  ext4l: Add write support and buffer mapping for mount
  ext4l: Use EXT4L_PRINTF to enable ext4 diagnostic messages
  ext4l: Document __CHAR_UNSIGNED__ behavior for directory hashing
  ext4l: Implement super_set_uuid() to display filesystem UUID
  ext4l: Add message buffer to record ext4 messages
  ext4l: Add ext4l_msgs env var to print messages on mount
  test: fs: Add ext4l filesystem tests
  ext4l: Export ext4_readdir() for directory listing
  ext4l: Fix dir_emit() to call the actor callback
  ext4l: Add ls command support
