NAMEbtrfs-quota - control the quota of a btrfs filesystem
btrfs quota <subcommand> <args>
btrfs quota is used to enable/disable or rescan subvolume quota of a btrfs filesystem.
For setting quota or other quota operations on a btrfs filesystem, please see btrfs-qgroup(8) for details.
Quota and qgroup in btrfs filesystem is not stable and impacts performance in mainline kernel yet(v3.14 so far).

- Enable subvolume quota support for a filesystem.
rescan [-s] <path>
Trash all qgroup numbers and scan the metadata again with the current config.

- wait for rescan operation to finish(can be already in progress).
btrfs quota returns a zero exit status if it succeeds. Non zero is returned in case of failure.
