  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).
