Chris Wilson	52dfa038b9	snapshot: Avoid triggering assertion for grabbing the target during destroy ... If the source wins the race to acquire the original surface as it is being destroyed, it triggers an assertion. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>	2012-05-01 16:55:22 +01:00
Chris Wilson	7eb33099d3	snapshot: Perform the cow under a mutex ... In order to prevent a race between concurrent destroy and use in another thread, we need to acquire a reference to the snapshot->target under a mutex. Whilst we hold that reference, it prevents the internal destroy mechanism from freeing the memory we are using (if we have a pointer to the original surface) and the client drops their final reference. Oh boy, talk about opening a can of worms... Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>	2012-04-27 14:10:50 +01:00
