From 0b9fd3f467dc5ac041fa014cd28c949b25b87d25 Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Tue, 10 Jul 2018 14:31:17 +0800 Subject: block: Use BdrvChild to discard Other I/O functions are already using a BdrvChild pointer in the API, so make discard do the same. It makes it possible to initiate the same permission checks before doing I/O, and much easier to share the helper functions for this, which will be added and used by write, truncate and copy range paths.
