The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h in the Linux kernel
before 4.13.2 does not verify that a filesystem has a realtime device,
which allows local users to cause a denial of service (NULL pointer
dereference and OOPS) via vectors related to setting an RHINHERIT flag on a
directory.
