From: Mathieu Desnoyers Date: Thu, 9 Jun 2011 15:27:11 +0000 (-0400) Subject: Update liburcu version check X-Git-Tag: v1.9.1~352 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=cfa0520d911287f5c470d74272c578bc041077bf;p=lttng-ust.git Update liburcu version check liburcu symbols have changed (_bp suffix added for the -bp flavor used by UST), and we now depend on urcu 0.5.5 for struct rcu_head definition. Therefore, check for synchronize_rcu_bp and call_rcu_bp.
