Subject: [PATCH 09/14] ide: inline task_in_unexpected() into task_pio_intr()
Date: Mon, 02 Feb 2009 22:38:14 +0100	[thread overview]
Message-ID: <20090202213814.17960.32694.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20090202213707.17960.61897.sendpatchset@localhost.localdomain>

Subject: [PATCH] ide: inline task_in_unexpected() into task_pio_intr()

task_in_unexpected() is only used by task_pio_intr() so inline it there.

There should be no functional changes caused by this patch.
