Subject: [PATCH 1/3] kernel/srcu: merge common code into a macro
Date: Tue, 19 Mar 2013 15:16:44 +0100 [thread overview]
Message-ID: <1363702606-31586-1-git-send-email-bigeasy@linutronix.de> (raw)
DEFINE_SRCU() and DEFINE_STATIC_SRCU() does the same thing except for
the "static" attribute. This patch moves the common pieces into
_DEFINE_SRCU() which is used by the the former macros either adding the
static attribute or not.
