From d9a9cdfb078d755e648d53ec25b7370f84ee5729 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Thu, 15 Mar 2007 15:50:34 -0400 Subject: [PATCH] sysfs and driver core: add callback helper, used by SCSI and S390 This patch (as868) adds a helper routine for device drivers that need to set up a callback to perform some action in a different process's context. This is intended for use by attribute methods that want to unregister themselves or their parent device. Attribute method calls are mutually exclusive with unregistration, so such actions cannot be taken directly. Two attribute methods are converted to use the new helper routine: one for SCSI device deletion and one for System/390 ccwgroup devices.
