In the Linux kernel, the following vulnerability has been resolved:
page_pool: avoid infinite loop to schedule delayed worker
We noticed the kworker in page_pool_release_retry() was waken
up repeatedly and infinitely in production because of the
buggy driver causing the inflight less than 0 and warning
us in page_pool_inflight()[1].
Since the inflight value goes negative, it means we should
not expect the whole page_pool to get back to work normally.
This patch mitigates the adverse effect by not rescheduling
the kworker when detecting the inflight negative in
page_pool_release_retry().

Note: before this patch, the above calltrace would flood the
dmesg due to repeated reschedule of release_dw kworker.
