Do you prefer:
a) make a function
sys.c: ksetgroups(int gidsetsize, gid_t *grouplist)
which does the same as sys_setgroups, but without the copy_from_user()
stuff? The only user (for now, maybe ever) is nfsd.
b) make a function
sys.c: nfsd_setgroups(int gidsetsize, gid_t *grouplist)
which does the same as sys_setgroups, but without the copy_from_user()
c) make the nfsd code build a struct group_info and call
set_current_groups()
