[PATCH] zd1211rw: Added workqueue
From: Daniel Drake <hidden>
Date: 2006-09-13 01:37:24
From: Ulrich Kunitz <redacted> For housekeeping and watchdog tasks a workqueue is created. The central workqueue is not used to prevent crashes creates by bugs. It might be changed, when the housekeeping is stabilized.
