Subject: nfsd: move nfserrno() to vfs.c
From: Jeff Layton <jlayton@xxxxxxxxxx>
[ Upstream commit cb12fae1c34b1fa7eaae92c5aadc72d86d7fae19 ]
nfserrno() is common to all nfs versions, but nfsproc.c is specifically
for NFSv2. Move it to vfs.c, and the prototype to vfs.h.
While we're in here, remove the #ifdef EDQUOT check in this function.
It's apparently a holdover from the initial merge of the nfsd code in
1997. No other place in the kernel checks that that symbol is defined
before using it, so I think we can dispense with it here.
