Hi Dmitry, > So wrap 'netfs_prepare_read_iterator()' to handle all possible > -ENOMEM cases and mark the corresponding subrequest as cancelled. I think there's a slightly better way to do it. There are three users of netfs_prepare_read_iterator() but there's also the call to ->prepare_read() which I think can all be combined. (And I've just realised that the patch I asked syzbot to test has a bug in it) David
