From 4bf021dbd5d4da22058d425dceae93ce11ff3700 Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Thu, 10 Jun 2021 14:25:44 +0300 Subject: [PATCH] block: rename bdrv_replace_child to bdrv_replace_child_tran We have bdrv_replace_child() wrapper on bdrv_replace_child_noperm(). But bdrv_replace_child() doesn't update permissions. It's rather strange, as normally it's expected that foo() should call foo_noperm() and update permissions. Let's rename and add comment.
