From: Bryan Schumaker Date: Tue, 3 Aug 2010 17:04:00 +0000 (-0400) Subject: NFS: Fix /proc/mount for legacy binary interface X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d5eff1a3412f6d75bf28f423c5015ece8055407a;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git NFS: Fix /proc/mount for legacy binary interface Add a flag so we know if we mounted the NFS server using the legacy binary interface. If we used the legacy interface, then we should not show the mountd options.
