    fix create_new_namespaces() return value · 467e9f4b
    Cedric Le Goater authored
    dup_mnt_ns() and clone_uts_ns() return NULL on failure.  This is wrong,
    create_new_namespaces() uses ERR_PTR() to catch an error.  This means that the
    subsequent create_new_namespaces() will hit BUG_ON() in copy_mnt_ns() or
    copy_utsname().
    
    Modify create_new_namespaces() to also use the errors returned by the
    copy_*_ns routines and not to systematically return ENOMEM.
