       fsck.btrfs - do nothing, successfully

       fsck.btrfs [-aApy] [device...]

       fsck.btrfs  is  a  type of utility that should exist for any filesystem
       and is called during system setup  when	the  corresponding  /etc/fstab
       entries contain non-zero value for fs_passno , see fstab(5) for more.

       Traditional  filesystems	 need  to run their respective fsck utility in
       case the filesystem was not unmounted cleanly and the log needs	to  be
       replayed	 before	 mount.	 This  is not needed for BTRFS. You should set
       fs_passno to 0.

       If you wish to check the consistency of a BTRFS filesystem or repair  a
       damaged	filesystem,  see  btrfs(8)  subcommand 'check'. By default the
       filesystem consistency is checked,  the	repair	mode  is  enabled  via
       --repair option (use with care!).

       The  options  detect  if fsck.btrfs is executed in non-interactive mode
       and exits with success, otherwise prints a message about btrfs check.

       There are two possible exit code returned:

	      0	   No errors

	      8	   Operational error, eg. device does not exist
