  ext4: check superblock mapped prior to committing (2018-07-02 18:45:18 -0400)

Bug fixes for ext4; most of which relate to vulnerabilities where a
maliciously crafted file system image can result in a kernel OOPS or
hang.  At least one fix addresses an inline data bug could be
triggered by userspace without the need of a crafted file system
(although it does require that the inline data feature be enabled).

Jon Derrick (1):
      ext4: check superblock mapped prior to committing

Theodore Ts'o (14):
      ext4: add warn_on_error mount option
      ext4: add corruption check in ext4_xattr_set_entry()
      ext4: always verify the magic number in xattr blocks
      ext4: always check block group bounds in ext4_init_block_bitmap()
      ext4: make sure bitmaps and the inode table don't overlap with bg descriptors
      ext4: only look at the bg_flags field if it is valid
      ext4: verify the depth of extent tree in ext4_find_extent()
      ext4: include the illegal physical block in the bad map ext4_error msg
      ext4: clear i_data in ext4_inode_info when removing inline data
      ext4: never move the system.data xattr out of the inode body
      jbd2: don't mark block as modified if the handle is out of credits
      ext4: avoid running out of journal credits when appending to an inline file
      ext4: add more inode number paranoia checks
      ext4: add more mount time checks of the superblock
