From 7f1f86a0d04e79f8165e6f50d329a520b8cd11e5 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Tue, 13 Feb 2007 14:38:58 -0700 Subject: [PATCH] Fix SAK_work workqueue initialization. Somewhere in the rewrite of the work queues my cleanup of SAK handling got broken. Maybe I didn't retest it properly or possibly the API was changing so fast I missed something. Regardless currently triggering a SAK now generates an ugly BUG_ON and kills the kernel. Thanks to Alexey Dobriyan for spotting this. This modifies the use of SAK_work to initialize it when the data structure it resides in is initialized, and to simply call schedule_work when we need to generate a SAK. I update both data structures that have a SAK_work member for consistency. All of the old PREPARE_WORK calls that are now gone. If we call schedule_work again before it has processed it has generated the first SAK it will simply ignore the duplicate schedule_work request. Signed-off-by: Eric W.
