Re: [PATCH v9 13/14] ALSA: virtio: synchronize staged capture accounting during RESET

[sashiko-bot@kernel.org]

> Use the locked PCM reset operation for staged capture. Reclaim RX space
> at the same locked pointer observation used by the common reset and keep
> completions arriving after that observation. Rebase the notified-period
> counter there to avoid replaying old period notifications.
> 
> After common pointer mutation, finish the matching core rebase even if
> refill fails. Latch XRUN and schedule notification. RESET can return zero
> before the asynchronous error is visible; userspace still needs ordinary
> XRUN recovery. A nonblocking read can initially return -EAGAIN and later
> -EPIPE. This avoids leaving core and driver positions partly rebased.
> 
> A forced 90 ms RX interval reproduced -EPIPE with the earlier accounting.
> The corrected sequence matched the next 48,000 deterministic frames and
> passed reopen. Linked RESET and prepare partial-failure fixtures also
> passed with atomic and nonatomic stream locking.
