tools/io_uring: sync with liburing

2019-05-23T16:25:26+00:00

Various fixes and changes have been applied to liburing since we
copied some select bits to the kernel testing/examples part, sync
up with liburing to get those changes.

Most notable is the change that split the CQE reading into the peek
and seen event, instead of being just a single function. Also fixes
an unsigned wrap issue in io_uring_submit(), leak of 'fd' in setup
if we fail, and various other little issues.

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.
