Message-ID: <4720F775.8030702@hp.com> Date: Thu, 25 Oct 2007 16:07:17 -0400 From: Vlad Yasevich <vladislav.yasevich@...com> To: lkml <linux-kernel@...r.kernel.org> Cc: Herbert Xu <herbert@...dor.apana.org.au>, jens.axboe@...cle.com Subject: [PATCH] [CRYPTO]: Fix hmac_digest from the SG breakage. Crypto now uses SG helper functions. Fix hmac_digest to use those functions correctly and fix the oops associated with it.
