since COW semantics require touching directory entries all the way up
to the root of the subvolume, for transaction-intensive applications
it would make sense to provide something that works like "mkdir" but
creates a subvolume that will be mounted at a point rather than a
simple directory entry. To avoid contention serializing updates to the
root directory. Is something like that already in place?
