tools/io_uring: fix compile breakage

2020-09-21T13:50:58+00:00

It would seem none of the kernel continuous integration does this:
    $ cd tools/io_uring
    $ make

Otherwise it may have noticed:
   cc -Wall -Wextra -g -D_GNU_SOURCE   -c -o io_uring-bench.o
	 io_uring-bench.c
io_uring-bench.c:133:12: error: static declaration of ‘gettid’
	 follows non-static declaration
  133 | static int gettid(void)
      |            ^~~~~~
In file included from /usr/include/unistd.h:1170,
                 from io_uring-bench.c:27:
/usr/include/x86_64-linux-gnu/bits/unistd_ext.h:34:16: note:
	 previous declaration of ‘gettid’ was here
   34 | extern __pid_t gettid (void) __THROW;
      |                ^~~~~~
make: *** [: io_uring-bench.o] Error 1

The problem on Ubuntu 20.04 (with lk 5.9.0-rc5) is that unistd.h
already defines gettid(). So prefix the local definition with
"lk_".

tools/io_uring: remove IOCQE_FLAG_CACHEHIT

2019-04-08T16:48:50+00:00

This ended up not being included in the mainline version of io_uring,
so drop it from the test app as well.

io_uring: add a few test tools

2019-03-06T20:00:16+00:00

This adds two test programs in tools/io_uring/ that demonstrate both
the raw io_uring API (and all features) through a small benchmark
app, io_uring-bench, and the liburing exposed API in a simplified
cp(1) implementation through io_uring-cp.
