-Subject: [PATCH] Fix a race in the PRT wait for completion simple wait code
- for NVIDIA on the rt patch
-
--Note refactored again 160319.
-
--NOTE: this patch is a rebase of John Blackwood's patch. On his kernel, he must be using
--an older simple wait patch - as his applies to kernel/sched/core.c, while the simple wait
--completion code lives in kernel/sched/completion.c ... I have ported this to test with
--nvidia, as i would like to see if it fixes the semaphore issues i have seen.
-
--I've kept the original patch comment in tact;
-
-I'm not 100% sure that the patch below will fix your problem, but we
-saw something that sounds pretty familiar to your issue involving the
-nvidia driver and the preempt-rt patch. The nvidia driver uses the
-completion support to create their own driver's notion of an internally
-used semaphore.
-
-Fix a race in the PRT wait for completion simple wait code.
-
-A wait_for_completion() waiter task can be awoken by a task calling
-complete(), but fail to consume the 'done' completion resource if it
-looses a race with another task calling wait_for_completion() just as
-it is waking up.
-
-In this case, the awoken task will call schedule_timeout() again
-without being in the simple wait queue.
-
-So if the awoken task is unable to claim the 'done' completion resource,
-check to see if it needs to be re-inserted into the wait list before
-waiting again in schedule_timeout().
-
-Fix-by: John Blackwood <john.blackwood@ccur.com>
