Subject: [PATCH 1/9] timers: remove the fn and data arguments to call_timer_fn
Date: Tue, 16 May 2017 13:48:04 +0200 [thread overview]
Message-ID: <20170516114812.10660-2-hch@lst.de> (raw)
In-Reply-To: <20170516114812.10660-1-hch@lst.de>
And just move the dereferences inline, given that the timer gets
passed as an argument.
Signed-off-by: Christoph Hellwig <hch@lst.de>
