Modify the subvol and snapshot creation ioctls to work anywhere in the tree
This changes the snapshot and subvol ioctl API and command lines so that new snapshots and subvols can be created anywhere. Subvolume creation hasn't changed much: btrfsctl -S subvol_name directory This creates a new subvolume under 'directory' Snapshot creation looks the same, but is actually different: btrfsctl -s full_path_to_new_snapshot file_or_dir For example: btrfsctl -s /mnt/new_snap /mnt/subvol Will create a new snapshot named new_snap under /mnt of the root found in /mnt/subvol. It always snapshots the entire root regardless of which file or directory inside the root you give it. Signed-off-by: Chris Mason <>
