No action expected, just a FYI.

perf no longer builds in v6.1.y with Ubuntu 24.04 (glibc 2.39). The error is:

tests/bpf.c: In function ‘epoll_pwait_loop’:
tests/bpf.c:36:17: error: argument 2 null where non-null expected [-Werror=nonnull]
    36 |                 epoll_pwait(-(i + 1), NULL, 0, 0, NULL);
       |                 ^~~~~~~~~~~
In file included from tests/bpf.c:5:
/usr/include/x86_64-linux-gnu/sys/epoll.h:134:12: note: in a call to function ‘epoll_pwait’ declared ‘nonnull’
   134 | extern int epoll_pwait (int __epfd, struct epoll_event *__events,

The offending file was removed in v6.6+, so the problem is not seen there.

Again, this is just a FYI, with no action expected, just in case someone
tries to build this version of perf if glibc 2.39+ is installed.
