I had a problem with NFS mounts not allowing me access
using group membership/permissions which I traced to
kauth_cred_setgroups(..., UIO_SYSSPACE) in nfs_getreq()
returning EFAULT

Maybe kauth_cred_[gs]etgroups needs an extra mode to
use kcopy(), or change the nfs_getreq() call to use
UIO_USERSPACE, or something more complicated.
