[PATCH 5/6] Btrfs: make SNAP_DESTROY async

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is no reason to force an immediate commit when deleting a snapshot.
Users have some expectation that space from a deleted snapshot be freed
immediately, but even if we do commit the reclaim is a background process.

If users _do_ want the deletion to be durable, they can call 'sync'.
