From d05cc10406893dec65b8e89746e7d4c333935415 Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Thu, 19 Jan 2012 21:42:45 +0400 Subject: [PATCH] SUNRPC: ip map cache per network namespace cleanup This patch converts ip_map_cache per network namespace implemenetation to the same view, as other caches done in the series. Besides generalization, code becomes shorter with this patch. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust Acked-by: J.
