fsck.xfs is called by the generic Linux fsck(8) program at startup to check and repair an XFS filesystem.
XFS is a journaling filesystem and performs recovery at mount(8) time if necessary, so fsck.xfs simply
exits with a zero exit status.
If you wish to check the consistency of an XFS filesystem, or repair a damaged or corrupt XFS filesystem,
see xfs_repair(8).
However, the system administrator can force fsck.xfs to run xfs_repair(8) at boot time by creating a
/forcefsck file or booting the system with "fsck.mode=force" on the kernel command line.
