Most of that pile is putting name length into struct name_snapshot
and making use of it. Beginning of that series ("ovl_lookup_real_one():
don't bother with strlen()") ought to have been split in two (separate
switch of name_snapshot to struct qstr from overlayfs reaping the trivial
benefits of that), but I wanted to avoid a rebase - by the time I'd spotted
that it was (a) in -next and (b) close to 5.1-final ;-/
