As mentioned in the previous email, here are the three patches that add support for multiple waitqueues for polling with io_uring. Patches 1-2 are just basic prep patches, and should not have any functional changes in them. Patch 3 adds support for allocating a new io_poll_iocb unit if we get multiple additions through our queue proc for the wait queues. This new 'poll' addition is queued up as well, and it grabs a reference to the original poll request. Please do review, would love to get this (long standing) issue fixed as it's a real problem for various folks. -- Jens Axboe
