Hi!
This change also increases the size of kinfo_file structure, which won’t allow
programs not compiled against HEAD and working with kern.info.filedesc sysctl
to run properly on HEAD (e.g. 8.x, 9.x and 10.x jails won’t run properly on
HEAD,
and it also broke valgrind). Is there absolutely no way to avoid extending the
size
of this struct?
Thanks!
