From 62a6c300f18a9f6994baf6d767985425d48de427 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Wed, 24 Aug 2022 11:50:44 +0200 Subject: [PATCH] block: add missed block_acct_setup with new block device init procedure Commit 5f76a7aac156ca75680dad5df4a385fd0b58f6b1 is looking harmless from the first glance, but it has changed things a lot. 'libvirt' uses it to detect that it should follow new initialization way and this changes things considerably. With this procedure followed, blockdev_init() is not called anymore and thus block_acct_setup() helper is not called. This means in particular that defaults for block accounting statistics are changed and account_invalid/account_failed are actually initialized as false instead of true originally. This commit changes things to match original world. There are the following constraints: * new default value in block_acct_init() is set to true * block_acct_setup() inside blockdev_init() is called before blkconf_apply_backend_options() * thus newly created option in block device properties has precedence if specified Signed-off-by: Denis V.
