Subject: [PATCH tip/core/rcu 43/52] rcu: Remove for_each_rcu_flavor() flavor-traversal macro
Date: Wed, 29 Aug 2018 15:38:45 -0700 [thread overview]
Message-ID: <20180829223854.4055-43-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20180829223830.GA1800@linux.vnet.ibm.com>
Now that there is only ever a single flavor of RCU in a given kernel
build, there isn't a whole lot of point in having a flavor-traversal
macro. This commit therefore removes it and converts calls to it to
straightline code, inlining trivial functions as appropriate.
