Subject: mm/filemap.c: remove include of hardirq.h
X-Git-Tag: v4.16-rc1~122^2~78
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=2b9fceb3b47b7c44fb04eef068f441e7b18daa68;p=users%2Fhch%2Fmisc.git

mm/filemap.c: remove include of hardirq.h

in_atomic() has been moved to include/linux/preempt.h, and the filemap.c
doesn't use in_atomic() directly at all, so it sounds unnecessary to
include hardirq.h.
