Revision 33844e665104b169a3a7732bdcddb40e4f82b335 authored by Al Viro on 22 December 2016, 02:55:02 UTC, committed by Al Viro on 23 December 2016, 04:00:22 UTC
Problem similar to ones dealt with in "fold checks into iterate_and_advance()" and followups, except that in this case we really want to do nothing when asked for zero-length operation - unlike zero-length iterate_and_advance(), zero-length iterate_all_kinds() has no side effects, and callers are simpler that way. That got exposed when copy_from_iter_full() had been used by tipc, which builds an msghdr with zero payload and (now) feeds it to a primitive based on iterate_all_kinds() instead of iterate_and_advance().
