2020-09-21tools/io_uring: fix compile breakageDouglas Gilbert1-2/+2
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: *** [<builtin>: 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_". Signed-off-by: Douglas Gilbert <dgilbert@interlog.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-04-08tools/io_uring: remove IOCQE_FLAG_CACHEHITJens Axboe1-28/+4
This ended up not being included in the mainline version of io_uring, so drop it from the test app as well. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-03-06io_uring: add a few test toolsJens Axboe1-0/+616
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. Signed-off-by: Jens Axboe <axboe@kernel.dk>
