Subject: [PATCHSET v2 0/3] io_uring: make POLL_ADD support multiple waitqs
Date: Wed, 12 Feb 2020 13:25:12 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
Here's v2 of the "let's make POLL_ADD work on everything" patchset. As
before, 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.
Changes since v1:
- Fix unused 'ret' variable in io_poll_double_wake()
- Fail if we get an attempt at a third waitqueue addition (Pavel)
