Subject: rcu: Remove unused local variable "cpu"
X-Git-Tag: v4.19-rc1~214^2^2~18
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ab6b82147f471e31d9397c95d523631b6c8953f2;p=thirdparty%2Fkernel%2Flinux.git

rcu: Remove unused local variable "cpu"

One danger of using __maybe_unused is that the compiler doesn't yell
at you when you remove the last reference, witness rcu_bind_gp_kthread()
and its local variable "cpu".  This commit removes this local variable.
