[PATCH 2/4] libxfs: don't propagate RTINHERIT -> REALTIME when there is no rtdev

["Darrick J. Wong" <darrick.wong@xxxxxxxxxx>]

From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

When creating a file inside a directory that has RTINHERIT set, only
propagate the REALTIME flag to the file if the filesystem actually has a
realtime volume configured.  Otherwise, we end up writing inodes that
trip the verifiers.
