Advisory locks don't directly prevent the contents of a file from
changing (or from being read). If you have a lock on a file, the file
can still change if someone writes to that file.

So, if a volume is released, the file contents can change while you have
a lock, yes. The stuff in gerrit 8197 doesn't really deal with that.
