Subject: [PATCH 01/10] libata: return boolean values from ata_is_*
Date: Thu, 14 Jul 2016 09:05:42 +0900 [thread overview]
Message-ID: <1468454751-12466-2-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1468454751-12466-1-git-send-email-hch@lst.de>
This way we don't have to worry about the exact bit postition of the
test to leak out and any crazy propagation effects in the callers.
