FYI there is an old warning (not relevant to this change), not sure if it's an
false positive or how to fix it:

mem.c: In function ‘write_cpusets’:
mem.c:555:52: warning: ‘/online’ directive output may be truncated writing 7 bytes into a region of size between 1 and 8192 [-Wformat-truncation=]
  555 |                         snprintf(path1, BUFSIZ, "%s/online", path);
      |                                                    ^~~~~~~ 

Kind regards,
Petr
