Subject: [PATCH] NFSD: don't report compiled-out versions as present
Date: Fri, 14 May 2010 15:33:36 +0400	[thread overview]
Message-ID: <4BED3510.80403@openvz.org> (raw)

The /proc/fs/nfsd/versions file calls nfsd_vers() to check whether
the particular nfsd version is present/available. The problem is
that once I turn off e.g. NFSD-V4 this call returns -1 which is
true from the callers POV which is wrong.

The proposal is to report false in that case.

Patch is against git://linux-nfs.org/~bfields/linux:master
