tools/io_uring: fix compile breakage
[ Upstream commit 72f04da48a
]
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_".
