fsck.xfs exists only because linux automatically runs fsck against all filesystems as part of the boot process. When fsck.xfs is run, it simply returns a successful message back to fsck so the boot process can continue.  When the boot process subsequently mounts the xfs filesystem, xfs_check is run to determine if the filesystem is "dirty" and then the journal is played back and/or xfs_repair will be called to do the actual fixing.
