From 22931a15336e8b7726965c699981fd108620014b Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Tue, 10 Jul 2018 14:31:18 +0800 Subject: [PATCH] block: Use uint64_t for BdrvTrackedRequest byte fields This matches the types used for bytes in the rest parts of block layer. In the case of bdrv_co_truncate, new_bytes can be the image size which probably doesn't fit in a 32 bit int.
