lock_kiovec question

lock_kiovec tries to lock each page in the kiovec, and fails if it can't
lock one of the pages.

What if the zero page is mapped multiple times in the kiobuf?

AFAICS map_user_pages doesn't break zero page mappings if it's called
with rw==WRITE (i.e write to disk, read from kiobuf)
