The first three patches in this series implement an RCU library
within Open vSwitch. The library is self-contained; it does not
depend on liburcu or another external library. (This is the
primary difference between this series and the previous RFC
version.)
The fourth patch adds one simple user of the RCU library.
The remaining patches add RCU support for dpif-netdev.
Ben Pfaff (8):
ovs-atomic: Refactor declarations for GCC 4+, pthreads
implementations.
ovs-atomic: Add support for atomic pointer types.
ovs-rcu: New library.
ofproto: Use RCU to protect rule_actions.
util: New functions for allocating memory while avoiding false
sharing.
ovs-thread: Replace ovsthread_counter by more general ovsthread_stats.
dpif-netdev: Use ovsthread_stats for flow stats.
dpif-netdev: Use RCU to protect data.
