[PATCH] xfs: kill time.h

To: xfs@xxxxxxxxxxx
Subject: [PATCH] xfs: kill time.h
From: Dave Chinner <david@xxxxxxxxxxxxx>
Date: Mon, 29 Sep 2014 11:41:51 +1000
Delivered-to: xfs@xxxxxxxxxxx
From: Dave Chinner <dchinner@xxxxxxxxxx>

The typedef for timespecs and nanotime() are completely unnecessary,
and delay() can be moved to fs/xfs/linux.h, which means this file
can go away.
