io_uring: rename trace_io_uring_submit_sqe() tracepoint

2023-04-03T13:16:15+00:00

It has nothing to do with the SQE at this point, it's a request submission. While in there, get rid of the 'force_nonblock' argument which is also dead, as we only pass in true. Signed-off-by: Jens Axboe

io_uring: trace local task work run

2022-09-21T16:30:42+00:00

io_uring: Add tracepoint for short writes

2022-07-25T00:39:32+00:00

This adds the io_uring_short_write tracepoint to io_uring. A short write is issued if not all pages that are required for a write are in the page cache and the async buffered writes have to return EAGAIN.

io_uring: add trace event for running task work

This is useful for investigating if task_work is batching Signed-off-by: Dylan Yudaken Link: https://lore.kernel.org/r/20220622134028.2013417-8-dylany@fb.com Signed-off-by: Jens Axboe

io_uring: clean up tracing events

2022-07-25T00:39:14+00:00

We have lots of trace events accepting an io_uring request and wanting to print some of its fields like user_data, opcode, flags and so on. However, as trace points were unaware of io_uring structures, we had to pass all the fields as arguments. Teach trace/events/io_uring.h about struct io_kiocb and stop the misery of passing a horde of arguments to trace helpers.

io_uring: move io_uring_get_opcode out of TP_printk

2022-06-23T14:40:36+00:00

The TP_printk macro's are not supposed to use custom code ([1]) or else tools such as perf cannot use these events. Convert the opcode string representation to use the __string wiring that the event framework provides ([2]).

Pull io_uring NVMe command passthrough from Jens Axboe: "On top of everything else, this adds support for passthrough for io_uring. The initial feature for this is NVMe passthrough support, which allows non-filesystem based IO commands and admin commands. To support this, io_uring grows support for SQE and CQE members that are twice as big, allowing to pass in a full NVMe command without having to copy data around.

Pull io_uring socket() support from Jens Axboe: "This adds support for socket(2) for io_uring. This is handy when using direct / registered file descriptors with io_uring. Outside of those two patches, a small series from Dylan on top that improves the tracing by providing a text representation of the opcode rather than needing to decode this by reading the header file every time.
