Subject: NFSv4 only print the label when its queried
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=db053bdece3aa812d4da8c3aa2f15560618b9cc4;p=linux-block.git

NFSv4 only print the label when its queried

[ 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.
