Subject: NFS: Ensure we display the minor version correctly in /proc/mounts etc.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7bbceb6f2bdda67054bc66035a9543623e539126;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

NFS: Ensure we display the minor version correctly in /proc/mounts etc.

The 'minorversion' mount option is now deprecated, so we need to display
the minor version number in the 'vers=' format.
