Subject: [PATCHSET v3 0/3] Add support for registered waits
Date: Fri, 25 Oct 2024 08:12:57 -0600 [thread overview]
Message-ID: <20241025141403.169518-1-axboe@kernel.dk> (raw)
Hi,
v3 of the registered wait support, avoiding needless copies for doing
high frequency waits. For v1, see the posting here:
https://lore.kernel.org/io-uring/20241022204708.1025470-1-axboe@kernel.dk/T/#m2d1eb2cc648b9f9c292fd75fc6bc2a8d71eadd49
As with v1, find the kernel repo here:
https://git.kernel.dk/cgit/linux/log/?h=io_uring-reg-wait
and the liburing side here:

Since v2:
- Wrap registration with a setup struct, to better future proof the
feature. That would allow doing a registered wait variant with the
sigmask embedded as well, should that be interesting in the future.
- Update liburing reg-wait branch with the new registration API
- Fixup copy for 32 vs 64-bit
- Minor cleanups and comments
