Subject: [PATCHSET 0/3] io_uring: make POLL_ADD support multiple waitqs
Date: Mon, 10 Feb 2020 13:56:47 -0700
Message-ID: <> (raw)

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.
