From 08ef7bd3bc04261d14d570ac7eaac3eac947b1ba Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 18 Oct 2011 16:11:49 -0700 Subject: NFSv4: Translate NFS4ERR_BADNAME into ENOENT when applied to a lookup Both LOOKUP and OPEN operations may return NFS4ERR_BADNAME if we send a an invalid name as a filename argument. As far as the application is concerned, it just has to know that the file doesn't exist, and so ENOENT would be the appropriate reply. We should only return EINVAL if the filename is being used to _create_ a new object on the remote filesystem.
