Subject: [PATCH] test: disable prefault tests on xfs
ctl_prefault test verifies that the functionality of prefaulting works
by using indirect information, which for xfs returns incorrect information.
There's nothing file system-specific in the way prefaulting works,
so verifying it works only on one file system (ext4) is enough.
