Subject: [PATCHSET 0/3] io_uring: make POLL_ADD support multiple waitqs
Date: Mon, 10 Feb 2020 13:56:47 -0700 [thread overview]
Message-ID: <20200210205650.14361-1-axboe@kernel.dk> (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.
