linux-stable.git/tools/testing/selftests/pidfd, branch v6.15 Linux kernel stable tree selftests/pidfd: fixes syscall number defines 2025-03-25T13:59:05+00:00 Oleg Nesterov oleg@redhat.com 2025-03-23T17:45:18+00:00 8661bb9c717a07b7636224339fe8818b65db6ddf I had to spend some (a lot;) time to understand why pidfd_info_test (and more) fails with my patch under qemu on my machine ;) Until I applied the patch below. I think it is a bad idea to do the things like #ifndef __NR_clone3 #define __NR_clone3 -1 #endif because this can hide a problem. My working laptop runs Fedora-23 which doesn't have __NR_clone3/etc in /usr/include/. So "make" happily succeeds, but everything fails and it is not clear why.

I had to spend some (a lot;) time to understand why pidfd_info_test
(and more) fails with my patch under qemu on my machine ;) Until I
applied the patch below.

I think it is a bad idea to do the things like

	#ifndef __NR_clone3
	#define __NR_clone3 -1
	#endif

because this can hide a problem. My working laptop runs Fedora-23 which
doesn't have __NR_clone3/etc in /usr/include/. So "make" happily succeeds,
but everything fails and it is not clear why.
