[AF_UNIX]: Convert to use a spinlock instead of rwlock
From: Benjamin LaHaise <bcrl@kvack.org> In af_unix, a rwlock is used to protect internal state. At least on my P4 with HT it is faster to use a spinlock due to the simpler memory barrier used to unlock. This patch raises bw_unix to ~690K/s. Signed-off-by: David S. Miller <davem@davemloft.net>
