Subject: fs/dcache: include wait.h
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.9/older/patches-4.9.20-rt16.tar.xz
Since commit d9171b934526 ("parallel lookups machinery, part 4 (and
last)") dcache.h is using but does not include wait.h. It works as long
as it is included somehow earlier and fails otherwise.
