It looks like new_read can return NULL only if it's called with NF_GET or NF_PREFETCH. dm_bufio_read calls it with NF_READ, which means it shouldn't return NULL. Someone more familiar with dm-bufio, please correct me if I'm wrong. Sami -- dm-devel mailing list dm-devel@redhat.com https://www.redhat.com/mailman/listinfo/dm-devel
