[PATCH 09/30] staging: sync: Allow async waits to be canceled

From: Erik Gilling In order to allow drivers to cleanly handled teardown we need to allow them to cancel pending async waits. To do this cleanly, we move allocation of sync_fence_waiter to the driver calling sync_async_wait(). Cc: Maarten Lankhorst Cc: Erik Gilling Cc: Daniel Vetter Cc: Rob

[PATCH 12/30] staging: sync: Reorder sync_fence_release

From: Erik Gilling Previously fence's pts were freed before the were the fence was removed from the global fence list. This led to a race with the debugfs support where it would iterate over sync_pts that had been freed. Cc: Maarten Lankhorst Cc: Erik Gilling Cc: Daniel Vetter Cc: Rob Clark

[PATCH 13/30] staging: sync: Optimize fence merges

From: Erik Gilling If the two fences being merged contain sync_pts from the same timeline, those two pts will be collapsed into a single pt representing the latter of the two. Cc: Maarten Lankhorst Cc: Erik Gilling Cc: Daniel Vetter Cc: Rob Clark Cc: Sumit Semwal Cc: Greg KH Cc: dri-devel

[PATCH 14/30] staging: sync: Add internal refcounting to fences

From: Erik Gilling If a fence is released while a timeline that one of it's pts is on is being signaled, it is possible for that fence to be deleted before it is signaled. This patch adds a refcount for internal references such as signaled pt processing. Cc: Maarten Lankhorst Cc: Erik Gilling

[PATCH 15/30] staging: sync: Add reference counting to timelines

From: Erik Gilling If a timeline is destroyed while fences still hold pts on it, the reworked fence release handler can cause the timeline to be freed before all it's points are freed. Cc: Maarten Lankhorst Cc: Erik Gilling Cc: Daniel Vetter Cc: Rob Clark Cc: Sumit Semwal Cc: Greg KH Cc: d

[PATCH 22/30] staging: sync: Protect unlocked access to fence status

From: Erik Gilling Fence status is checked outside of locks in both sync_fence_wait and sync_fence_poll. This patch adds propper barrier protection in these cases to avoid seeing stale status. Cc: Maarten Lankhorst Cc: Erik Gilling Cc: Daniel Vetter Cc: Rob Clark Cc: Sumit Semwal Cc: Greg

[PATCH 23/30] staging: sync: Update new fence status with sync_fence_signal_pt

From: Erik Gilling If a fence's pt is signaled before sync_fence_create is called, the fence will never transition into the signaled state. This also address a tiny race if a merged fence's pt after sync_fence_get_status checks it's status and before fence->status is updated. Cc: Maarten Lankho
