The next "struct seq" introduced in patch 4 should be useful outside
dpif-netdev; it is a general-purpose synchronization data structure.
Ben Pfaff (5):
ovs-thread: New function xpthread_setspecific().
ovs-thread: Add support for globally visible per-thread data.
ovs-thread: New function ovsthread_id_self()
seq: New module for race-free, pollable, thread-safe sequence number.
dpif-netdev: Avoid race in dpif_netdev_port_poll_wait() using seq
object.
