CIFS: Fix wrong filename length for SMB2
The existing code uses the old MAX_NAME constant. This causes XFS test generic/013 to fail. Fix it by replacing MAX_NAME with PATH_MAX that SMB1 uses. Also remove an unused MAX_NAME constant definition. Cc: <stable@vger.kernel.org> # v3.7+ Signed-off-by: Pavel Shilovsky <pshilovsky@samba.org> Signed-off-by: Steve French <smfrench@gmail.com>
