From c4a4d603796c727b9555867571f89483be9c565e Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 16 Nov 2011 23:15:31 -0800 Subject: userns: Use cred->user_ns instead of cred->user->user_ns Optimize performance and prepare for the removal of the user_ns reference from user_struct. Remove the slow long walk through cred->user->user_ns and instead go straight to cred->user_ns. Acked-by: Serge Hallyn Signed-off-by: Eric W.
