Message-ID: <20120328064407.GG16191@secunet.com> Date: Wed, 28 Mar 2012 08:44:07 +0200 From: Steffen Klassert <steffen.klassert@...unet.com> To: Herbert Xu <herbert@...dor.apana.org.au> Cc: Peter Zijlstra <peterz@...radead.org>, linux-kernel@...r.kernel.org, linux-crypto@...r.kernel.org Subject: [PATCH 3/3] padata: Fix cpu hotplug We don't remove the cpu that went offline from our cpumasks on cpu hotplug. This got lost somewhere along the line, so restore it. This fixes a hang of the padata instance on cpu hotplug.
