xfs: probe the scrub ioctl
Create a probe scrubber with id 0. This will be used by xfs_scrub to probe the kernel's abilities to scrub (and repair) the metadata. We do this by validating the ioctl inputs from userspace, preparing the filesystem for a scrub (or a repair) operation, and immediately returning to userspace. Userspace can use the returned errno and structure state to decide (in broad terms) if scrub/repair are supported by the running kernel. Signed-off-by: Darrick J.
