>Description:
        
nfs_syscalls.c contains "extern int nuidhash_max;", but nuidhash_max only
resides in nfs_iod.c, which is a client-only NFS file.  So, kernels that
have NFSSERVER but not the NFS filesystem, fail to build.

>How-To-Repeat:
        
Try and build a kernel with NFSSERVER but not NFS.  Enjoy.

>Fix:
        
Replace "extern int nuidhash_max;" with the definition from nfs_iod.c, which
is "int nuidhash_max = NFS_MAXUIDHASH;".  This should probably go to some
common header file, but...this fix makes the kernel build. :-)
