From f6af99ec1b261e21219d5eba99e3af48fc6c32d4 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Tue, 4 Jan 2011 18:02:15 -0500 Subject: [PATCH] nfsd4: name->id mapping should fail with BADOWNER not BADNAME According to rfc 3530 BADNAME is for strings that represent paths; BADOWNER is for user/group names that don't map. And the too-long name should probably be BADOWNER as well; it's effectively the same as if we couldn't map it.
