The new dependency is not especially clear to me; more explanation
in the patch description about the cause of the build failure
would definitely be helpful.
NFSD_V4 can't be set unless NFSD is also set.
NFS_V4_2 can't be set unless NFS_V4_1 is also set, and that cannot
be set unless NFS_FS is also set.
So what's really going on here?
