From 2c52c8376db7160a1dd8a681c61c9258405ef143 Mon Sep 17 00:00:00 2001 From: Olga Kornievskaia Date: Mon, 29 Nov 2021 15:33:56 -0500 Subject: NFSv4 only print the label when its queried When the bitmask of the attributes doesn't include the security label, don't bother printing it. Since the label might not be null terminated, adjust the printing format accordingly.
