[PATCH 10/8] common/rc: test that the xfs_io scrub/repair commands actually work

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When we call _require_xfs_io_command for the scrub ioctl, we have to
actually try calling the ioctl to make sure that the ioctl is present on
the running kernel.
