Subject: MINOR: haload: enable per-thread-group FD tables when available
X-Git-Tag: v3.5-dev6~42
X-Git-Url: https://git.kaiwu.me/?a=commitdiff_plain;h=dd13b6f3f5eb44e8f21c2996ab721cb435b7bb81;p=haproxy.git

MINOR: haload: enable per-thread-group FD tables when available

Add <_GNU_SOURCE> so <CLONE_FILES> is visible from <sched.h>. When it
is, generate "expose-experimental-directives" and "tune.fd.tables
per-thread-group" in the global section.
