[Xen-devel] unregister_xenbus_watch() handling of xenwatch_mutex

["Jan Beulich" <jbeulich@xxxxxxxxxx>]

2.6.23 acquires the mutex before canceling pending events, whereas
linux-2.6.18-xen acquires and releases the mutex back-to-back after
doing the cancellation. It would seem to me that the former method is
more robust, but otoh I'm wondering why this change then wasn't also
made in the 2.6.18 tree.

Thanks, Jan
