This will leak the vm_struct and also leave it in the vmlist.
work_free_thread_info() needs to be redone too. It should be
remove_vm_area( /* unmap and remove the vm_struct from vmlist */ );
kfree( /* free the vm_struct */ );
for (i = 0; i < THREAD_SIZE/PAGE_SIZE; ++i)
__free_page( /* dredge up the appropriate page to free */ );
