This enables the 'btrsubvol' command to list subvolumes
|
||||||
|
of a BTRFS filesystem. There are no special commands for
|
||||||
|
listing BTRFS directories or loading BTRFS files - this
|
||||||
|
can be done by the generic 'fs' commands (see CMD_FS_GENERIC)
|
||||||
|
when BTRFS is enabled (see FS_BTRFS).
