* notifier: switch to QLISTPaolo Bonzini2012-02-171-5/+5
| | | | | | | | Notifiers do not need to access both ends of the list, and using a QLIST also simplifies the API. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

* notifier: Pass data argument to callbackJan Kiszka2011-07-231-2/+2
| | | | | | | | | | | This allows to pass additional information to the notifier callback which is useful if sender and receiver do not share any other distinct data structure. Will be used first for the clock reset notifier. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* Add support for generic notifier listsAnthony Liguori2010-03-191-0/+39
Notifiers are data-less callbacks and a notifier list is a list of registered notifiers that all are interested in a particular event. We'll use this in a few patches to implement mouse change notification. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> --- v1 -> v2 - Do not do memory allocations by placing list nodes in notifier
