From: Alexander Gordeev
Date: Mon Mar 09 2015 - 04:34:28 EST


Hi Paul,

Here is cleanup of RCU tree initialization rebased on linux-rcu rcu/next
repo, as you requested. Please, note an extra patch #10 that was not
present in the first post.

The series successfully passes kernel build test with CONFIG_RCU_FANOUT
and CONFIG_RCU_FANOUT_LEAF equal to 5.
