Subject: Fix: rename RCU_DEBUG to DEBUG_RCU in urcu-qsbr.h
X-Git-Tag: v0.8.7~2
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=65e14860489c5f903bbf5f6bd2d538e836cb5717;p=userspace-rcu.git

Fix: rename RCU_DEBUG to DEBUG_RCU in urcu-qsbr.h

Keep a mapping allowing to define RCU_DEBUG within urcu-qsbr.h for
compatibility purposes.
