Ugh. That sounds like a work for mount(8), not mount(2), then. BTW, userland
(mount(8)) looks like the only potential user for that.

OK... I don't like the idea of passing a vfsmount to read_super (for obvious

What kind of use (aside of getting rid of <not available> in dumpe2fs
output) do you have in mind?
