Can it unmount ALL folders for given LUKS mapper device?

Hi, Can it unmount ALL mounted folders for given LUKS mapper?

E.g. say there's USB drive with multiple mounted partitions/BTRFS subvolumes, and it can be tedious to go over each of them.

I guess this may be a feature request. One could check "lsof" or "mount" outputs.

Otherwise if everything in the script gets well commented, I might add this functionality myself. Thank you.
