Not in the current form: the kfunc validates the entire snapshot first so that invalid input leaves the globals untouched, and no abort path exists once the write loop begins, so a half-written mapping can't occur. It's also only callable from init_cids, before any scheduling reader exists. No change. Thanks. -- tejun
