From 2f10fdcb6a1c5f26246339d3b606131fae483c44 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 23 Mar 2017 16:57:36 +0800 Subject: [PATCH] nfsd4: remove pointless strdup_if_nonnull kstrdup() already checks for NULL. (Brought to our attention by Jason Yann noticing (from sparse output) that it should have been declared static.) Signed-off-by: NeilBrown Reported-by: Jason Yan Signed-off-by: J.
