BTW Stefan, I got: "[RFC PATCH v4 0/4] liburing: add api for napi busy poll" patchset twice. Both are identical. But I don't get a v4 kernel patchset that adds this feature. Maybe you were going to send the kernel and liburing patchset, but you accidentally sent the liburing patchset twice?

Did you post the kernel side, because I don't see it? That's the most important one to get sorted first.
This adds two new api's to set/clear the napi busy poll settings. The two new functions are called: - io_uring_register_napi - io_uring_unregister_napi The patch series also contains the documentation for the two new functions and two example programs. The client program is called napi-busy-poll-client and the server program napi-busy-poll-server. The client measures the roundtrip times of requests. There is also a kernel patch "io-uring: support napi busy poll" to enable this feature on the kernel side. Changes: - V4: - Modify functions to use a structure to pass the napi busy poll settings to the kernel. - Return previous values when returning from the above functions. - Rename the functions and remove one function (no longer needed as the data is passed as a structure) - V3: - Updated liburing.map file - Moved example programs from the test directory to the example directory. The two example programs don't fit well in the test category and need to be run from separate hosts. - Added the io_uring_register_napi_prefer_busy_poll API. - Added the call to io_uring_register_napi_prefer_busy_poll to the example programs - Updated the documentation - V2: - Updated the liburing.map file for the two new functions. (added a 2.4 section) - Added a description of the new feature to the changelog file - Fixed the indentation of the longopts structure - Used defined exit constants - Fixed encodeUserData to support 32 bit builds Signed-off-by: Stefan Roesch <shr@devkernel.io> *** BLURB HERE *** Stefan Roesch (4): liburing: add api to set napi busy poll settings liburing: add documentation for new napi busy polling liburing: add example programs for napi busy poll liburing: update changelog with new feature .gitignore | 2 + CHANGELOG | 3 + examples/Makefile | 2 + examples/napi-busy-poll-client.c | 441 +++++++++++++++++++++++++++++++ examples/napi-busy-poll-server.c | 385 +++++++++++++++++++++++++++ man/io_uring_register_napi.3 | 40 +++ man/io_uring_unregister_napi.3 | 27 ++ src/include/liburing.h | 3 + src/include/liburing/io_uring.h | 12 + src/liburing.map | 6 + src/register.c | 12 + 11 files changed, 933 insertions(+) create mode 100644 examples/napi-busy-poll-client.c create mode 100644 examples/napi-busy-poll-server.c create mode 100644 man/io_uring_register_napi.3 create mode 100644 man/io_uring_unregister_napi.3 base-commit: 8fc22e3b3348c0a6384ec926e0b19b6707622e58
