commit d08c84e01afa7a7eee6badab25d5420fa847f783 upstream. In fedora rawhide the PTHREAD_STACK_MIN define may end up expanded to a sysconf() call, and that will return 'long int', breaking the build: 45 fedora:rawhide : FAIL gcc version 11.1.1 20210623 (Red Hat 11.1.1-6) (GCC) builtin-sched.c: In function 'create_tasks': /git/perf-5.14.0-rc1/tools/include/linux/kernel.h:43:24: error: comparison of distinct pointer types lacks a cast [-Werror] 43 | (void) (&_max1 == &_max2); \ | ^~ builtin-sched.c:673:34: note: in expansion of macro 'max' 673 | (size_t) max(16 * 1024, PTHREAD_STACK_MIN)); | ^~~ cc1: all warnings being treated as errors $ grep __sysconf /usr/include/*/*.h /usr/include/bits/pthread_stack_min-dynamic.h:extern long int __sysconf (int __name) __THROW; /usr/include/bits/pthread_stack_min-dynamic.h:# define PTHREAD_STACK_MIN __sysconf (__SC_THREAD_STACK_MIN_VALUE) /usr/include/bits/time.h:extern long int __sysconf (int); /usr/include/bits/time.h:# define CLK_TCK ((__clock_t) __sysconf (2)) /* 2 is _SC_CLK_TCK */ $ So cast it to int to cope with that.
