From 73758fed711b847d833b9b0db59137eaeed06485 Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Wed, 14 Nov 2012 18:22:01 +0300 Subject: [PATCH] nfsd: make close_lru list per net This list holds nfs4 clients (open) stateowner queue for last close replay, which are network namespace aware. So let's make this list per network namespace too. Signed-off-by: Stanislav Kinsbursky Signed-off-by: J.
