Subject: MINOR: config: add a diag for invalid cpu-map statement
X-Git-Tag: v2.4-dev17~26
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a2944ecf5d3fd28fe1b7405840a068732bfa035c;p=thirdparty%2Fhaproxy.git

MINOR: config: add a diag for invalid cpu-map statement

If a cpu-statement is refering to multiple processes and threads, it is
silently ignored. Add a diag message to report it to the user.
