From 353a5d84b25c335b259f37c4f43dad96e6d60ba8 Mon Sep 17 00:00:00 2001 From: Alberto Faria Date: Thu, 9 Jun 2022 16:27:37 +0100 Subject: block: Make bdrv_{pread,pwrite}() return 0 on success They currently return the value of their 'bytes' parameter on success. Make them return 0 instead, for consistency with other I/O functions and in preparation to implement them using generated_co_wrapper. This also makes it clear that short reads/writes are not possible. The few callers that rely on the previous behavior are adjusted accordingly by hand.
