Hi Tomeu,
Patch subject: please put the version into the brackets, so [PATCH v5] as it shouldn't be part of the commit log.
Am Dienstag, 24. Mai 2016, 09:27:37 schrieb Tomeu Vizoso:
As per the docs, atomic_commit should return -EBUSY "if an asycnhronous updated is requested and there is an earlier updated pending".
v2: Use the status of the workqueue instead of vop->event, and don't add a superfluous wait on the workqueue.
v3: Drop work_busy, as there's a sizeable delay when the worker finishes, which introduces a race in which the client has already received the last flip event but the next page flip ioctl will still return -EBUSY because work_busy returns outdated information.
v4: Hold dev->event_lock while checking the VOP's event field as suggested by Daniel Stone.
v5: Only block if there's outstanding work if it's a blocking call.
similarly, please put the changelog below the "---" and above the diffstat.
