Subject: NFS: Enabling v4.2 should not recompile nfsd and lockd
X-Git-Tag: v4.13~8263^2~8
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=694e096fd7c2a7d40760fc9c9dfc826bdd495ea4;p=mirror_ubuntu-bionic-kernel.git

NFS: Enabling v4.2 should not recompile nfsd and lockd

When CONFIG_NFS_V4_2 is toggled nfsd and lockd will be recompiled,
instead of only the nfs client.  This patch moves a small amount of code
into the client directory to avoid unnecessary recompiles.
