    [PATCH] sysfs and driver core: add callback helper, used by SCSI and S390 · d9a9cdfb
    Alan Stern authored
    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.
