Subject: [PATCH liburing 00/11] Defer taskrun changes
Date: Mon, 15 Aug 2022 06:09:36 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
This series adds support to liburing for the IORING_SETUP_DEFER_TASKRUN flag.
The second half of the series is a bit mixed and includes some documentation
fixes, overflow cleanups and test cleanups. I sent these a couple of months
ago and forgot about it, but now it does depend on the new API so it needs to
be ordered.
I can send it separately if you like.
Patches:
1 copies the definition from the kernel include file
2 introduces new APIs required for this feature
3/4/5 add tests for IORING_SETUP_DEFER_TASKRUN
6/7/8 clean and update existing documentation to match upstream
9 exposes the overflow state to the application
10 uses this and tests overflow functionality
11 gives an explicit warning if there is a short read in file-verify
Dylan Yudaken (11):
Copy defer task run definition from kernel
add io_uring_submit_and_get_events and io_uring_get_events
add a t_probe_defer_taskrun helper function for tests
update existing tests for defer taskrun
add a defer-taskrun test
fix documentation shortenings
update io_uring_enter.2 docs for IORING_FEAT_NODROP
add docs for overflow lost errors
expose CQ ring overflow state
overflow: add tests
file-verify test: log if short read
