Date: Mon, 08 Feb 2016 23:53:51 +0000 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "Herbert Xu" <herbert@...dor.apana.org.au> Subject: [PATCH 3.2 78/87] crypto: algif_skcipher - Remove custom release parent function 3.2.77-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Herbert Xu <herbert@...dor.apana.org.au> commit d7b65aee1e7b4c87922b0232eaba56a8a143a4a0 upstream. This patch removes the custom release parent function as the generic af_alg_release_parent now works for nokey sockets too.
