From 1b5ab0def4f6e42e8b8097c3b11d2e8d96baafec Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Wed, 27 Mar 2013 05:55:56 +0000 Subject: net: use the frag lru_lock to protect netns_frags.nqueues update Move the protection of netns_frags.nqueues updates under the LRU_lock, instead of the write lock. As they are located on the same cacheline, and this is also needed when transitioning to use per hash bucket locking.
