Subject: [PATCHSET v2] Cancel requests at ring close time
Date: Fri, 11 Sep 2026 09:45:24 -0600 [thread overview]
Message-ID: <20260911154811.646705-1-axboe@kernel.dk> (raw)
Hi,
For v1, see here:
https://lore.kernel.org/io-uring/20260909141010.21064-1-axboe@kernel.dk/
And for the current tree, go here:
https://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux.git/log/?h=io_uring-exit-cancel.7
Changes since v1:
- Reorder the series so the fixes for the current tree come first,
then the exit/release cancelation changes on top
- Add fix for io-wq completions that finish asynchronously (eg a
direct read completing via ->ki_complete), ensuring CQE posting and
file putting are sane.
- Ditto for IOPOLL completions reaped from io_do_iopoll()
- Put request files synchronously before posting the CQEs in the batch
flush, fixing an issue with SQPOLL.
- Don't clear REQ_F_REFCOUNT from the completion path, a linked timeout
can still take a reference on the request until it's disarmed
