Subject: MINOR: backend: Do not always allow takeover across thread groups
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ca48527dd9066dbfa12c324818f5f254a6902cd0;p=thirdparty%2Fhaproxy.git

MINOR: backend: Do not always allow takeover across thread groups

Instead of silently ignoring tune.idle-pool.shared. full
if tune.fd.tables per-thread-group is set, have an error at startup if
both are set, as they are incompatible.
