Subject: [PATCH -mm 10/17] sysctl extern cleanup - block iopoll
Date: Sun, 21 Feb 2010 22:24:25 +0800 [thread overview]
Message-ID: <20100221142425.GA3016@darkstar> (raw)
Extern declarations in sysctl.c should be move to their own head file,
and then include them in relavant .c files.
blk_iopoll_enabled declared in linux/blk-iopoll.h, remove the declaration in
sysctl.c, include the head file instead.
