Subject: [PATCH 1/2] crypto: caam - Reintroduce DESC_MAX_USED_BYTES
Date: Thu, 18 Jun 2015 14:25:55 +0800 [thread overview]
Message-ID: <E1Z5TGt-0007Qo-2u@gondolin.me.apana.org.au> (raw)
In-Reply-To: 20150618061734.GA28418@gondor.apana.org.au
I incorrectly removed DESC_MAX_USED_BYTES when enlarging the size
of the shared descriptor buffers, thus making it four times larger
than what is necessary. This patch restores the division by four
calculation.
