From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>
This patch series de-stage the sync framework, and in order to accomplish that
a bunch of cleanups/improvements on the sync and fence were made.
The sync framework contained some abstractions around struct fence and those
were removed in the de-staging process among other changes:
Userspace visible changes
-------------------------
* The sw_sync file was moved from /dev/sw_sync to <debugfs>/sync/sw_sync. No
other change.
Kernel API changes
------------------
* struct sync_timeline is now struct fence_timeline
* sync_timeline_ops is now fence_timeline_ops and they now carry struct
fence as parameter instead of struct sync_pt
* a .cleanup() fence op was added to allow sync_fence to run a cleanup when
the fence_timeline is destroyed
* added fence_add_used_data() to pass a private point to struct fence. This
pointer is sent back on the .cleanup op.
* The sync timeline function were moved to be fence_timeline functions:
- sync_timeline_create() -> fence_timeline_create()
- sync_timeline_get() -> fence_timeline_get()
- sync_timeline_put() -> fence_timeline_put()
- sync_timeline_destroy() -> fence_timeline_destroy()
- sync_timeline_signal() -> fence_timeline_signal()
* sync_pt_create() was replaced be fence_create_on_timeline()
Internal changes
----------------
* fence_timeline_ops was removed in favor of direct use fence_ops
* fence default functions were created for fence_ops
* removed structs sync_pt, sw_sync_timeline and sw_sync_pt
