[PATCH 0/2] CQ vs SQ timeout accounting

From: Pavel Begunkov
Date: Sat Apr 18 2020 - 13:21:26 EST


The first patch do the job, and triggers after __any__ CQEs, including
ones from other timeouts. And it obviously fails to pass the tests. The
second patch makes it to count only non-timeout CQEs, and passes
the tests. Feel free to squash them.

Fixes Hrvoje's issue. Also, there is one more bug to be fixed.
It's related to bulk completion, and manifests itself with both
implementations.

Pavel Begunkov (2):
io_uring: trigger timeout after any sqe->off CQEs
io_uring: don't trigger timeout with another t-out
