NFSv3: Fix another acl regression
commit f87d928f6d98644d39809a013a22f981d39017cf upstream. When creating a new object on the NFS server, we should not be sending posix setacl requests unless the preceding posix_acl_create returned a non-trivial acl. Doing so, causes Solaris servers in particular to return an EINVAL. Fixes: 013cdf1088d72 (nfs: use generic posix ACL infrastructure,,,) Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1132786 Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
