Subject: [PATCHv3][trivial] crypto: tcrypt - reduce stack size
Date: Wed, 25 Feb 2009 15:53:14 +0100 [thread overview]
Message-ID: <49A55B5A.70705@suse.de> (raw)
In-Reply-To: <49A5549F.4070304@suse.de>
From: Frank Seidel <frank@f-seidel.de>
Applying kernel janitors todos (printk calls need KERN_*
constants on linebeginnings, reduce stack footprint where
possible) to tcrypts test_hash_speed (where stacks
memory footprint was very high (on i386 1184 bytes to
160 now).
