Add a flag argument to g_call_me() methods which will be used to signal cancellation of events in the future. This commit should be a no-op. Notes: svn path=/head/; revision=112988

* If we run out of consumers while orphaning them, and the provider's geomPoul-Henning Kamp2003-03-101-0/+5

* Implement g_call_me() as a way for geom methods to schedule operationsPoul-Henning Kamp2002-09-271-0/+30
| | | | | | | | | | | | | | | | | | | to be performed in the event-thread. To do this, we need to lock the eventlist with g_eventlock (nee g_doorlock), since g_call_me() being called from the UP/DOWN paths will not be able to aquire g_topology_lock. This also means that for now these events are not referenced on any particular consumer/provider/geom. For UP/DOWN path use, this will not become a problem since the access() function will make sure we drain any bio's before we dismantle. Sponsored by: DARPA & NAI Labs.

test and play with this. This is not yet production quality and should be run only on dedicated test boxes. For people who want to develop transformations for GEOM there exist a set of shims to run geom in userland (ask phk@freebsd.org). Reports of all kinds to: phk@freebsd.org Please include in report: dmesg sysctl debug.geomdot sysctl debug.geomconf Known significant limitations: no kernel dump facility. ioctls severely restricted.
