All genl callbacks are serialized by genl-mutex. This can become bottleneck in multi threaded case. Following patch adds an parameter to genl_family so that a particular family can get concurrent netlink callback without genl_lock held. New rw-sem is used to protect genl callback from genl family unregister. in case of parallel_ops genl-family read-lock is taken for callbacks and write lock is taken for register or unregistration for any family. In case of locked genl family semaphore and gel-mutex is locked for any openration. Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: David S. Miller <davem@davemloft.net> |
