Subject[PATCH 0/9] rcu: Cleanup RCU tree initialization
Date
Hello,

This is an attempt to make RCU tree initialization bit more
clear and optimize memory footprint of data associated with
the tree.

Cc: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

Alexander Gordeev (9):
rcu: Panic if RCU tree can not accommodate all CPUs
rcu: Remove superfluous local variable in rcu_init_geometry()
rcu: Cleanup rcu_init_geometry() code and arithmetics
rcu: Simplify rcu_init_geometry() capacity arithmetics
rcu: Limit rcu_state::levelcnt[] to RCU_NUM_LVLS items
rcu: Limit rcu_capacity[] size to RCU_NUM_LVLS items
rcu: Remove unnecessary fields from rcu_state structure
rcu: Limit count of static data to the number of RCU levels
rcu: Simplify arithmetic to calculate number of RCU nodes
