Do lazy-unmount to /storage directly

From man 2 umount:
MNT_DETACH (since Linux 2.4.11)

Perform a lazy unmount: make the mount point unavailable for new
accesses, immediately disconnect the filesystem and all filesystems
mounted below it from each other and from the mount table, and
actually perform the unmount when the mount point ceases to be busy.

So we don't need to unmount the filesystems under it one by one.
