From mboxrd@z Thu Jan 1 00:00:00 1970 From: Oleg Nesterov Subject: [PATCH 2/2] workqueues: export keventd_wq Date: Thu, 29 Apr 2010 21:45:45 +0200 Message-ID: <20100429194545.GC17280@redhat.com> References: <1272429119-12103-1-git-send-email-arve@android.com> <20100428194028.GA16389@redhat.com> <4BD89922.1040306@kernel.org> <201004282308.10751.rjw@sisk.pl> <20100429185851.GA13862@redhat.com> <20100429194447.GA17280@redhat.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Content-Disposition: inline In-Reply-To: <20100429194447.GA17280@redhat.com> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: linux-pm-bounces@lists.linux-foundation.org Errors-To: linux-pm-bounces@lists.linux-foundation.org To: "Rafael J. Wysocki" , Tejun Heo Cc: Len Brown , linux-kernel@vger.kernel.org, linux-pm@lists.linux-foundation.org List-Id: linux-pm@vger.kernel.org Export keventd_wq. Otherwise, any helper on top of queue_work() has to be copy-and-pasted to create the version which uses keventd_wq. Note: we can do more cleanups with this change and kill EXPORT_SYMBOLs, almost any function which currently uses keventd_wq can become the trivial inline.
