Subject[PATCH AUTOSEL 5.4 01/15] NFSv4 only print the label when its queried
Date
From: Olga Kornievskaia <kolga@netapp.com>

[ Upstream commit 2c52c8376db7160a1dd8a681c61c9258405ef143 ]

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.
