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. Cc: "Paul E. McKenney" <paul...@linux.vnet.ibm.com> Alexander Gordeev (10): 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 rcu: Remove unnecessary grpnum field from rcu_node structure kernel/rcu/tree.c | 102 ++++++++++++++++++++--------------------------- kernel/rcu/tree.h | 35 ++++++++-------- kernel/rcu/tree_plugin.h | 4 +- 3 files changed, 63 insertions(+), 78 deletions(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
