Functions
| btrfs_util_create_qgroup_inherit⚠ | btrfs_util_create_qgroup_inherit() - Create a qgroup inheritance specifier for btrfs_util_create_subvolume() or btrfs_util_create_snapshot(). @flags: Must be zero. @ret: Returned qgroup inheritance specifier. |

If %BTRFS_UTIL_CREATE_SNAPSHOT_RECURSIVE was in @flags, then this will contain the largest transaction ID of all created subvolumes. @qgroup_inherit: See btrfs_util_create_subvolume(). |

| btrfs_util_create_subvolume⚠ | btrfs_util_create_subvolume() - Create a new subvolume. @path: Where to create the subvolume. @flags: Must be zero. @async_transid: If not NULL, create the subvolume asynchronously (i.e., without waiting for it to commit it to disk) and return the transaction ID that it was created in.
