Subject: [PATCH 01/10] crypto: aead - allow to allocate AEAD requests on the stack
Date: Wed,  2 May 2018 11:57:16 +0200	[thread overview]
Message-ID: <20180502095725.31935-2-antoine.tenart@bootlin.com> (raw)
In-Reply-To: <20180502095725.31935-1-antoine.tenart@bootlin.com>

Adds the AEAD_REQUEST_ON_STACK primitive to allow allocating AEAD
requests on the stack, as it can already be done with various other
crypto algorithms within the kernel.
