# 5f062427 ("xfs_repair: validate alignment of inherited rt extent hints")
#
# This xfs_repair patch detects directories that are configured to propagate
# their realtime and extent size hints to newly created realtime files when the
# hint size isn't aligned to the size of a realtime extent.
#
# Since this is a test of userspace tool functionality, we don't need kernel
# support, which in turn means that we omit _require_realtime.  Note that XFS
# allows users to configure realtime extent size geometry and set RTINHERIT
# flags even if the filesystem itself does not have a realtime volume attached.
