Subject: [PULL 05/18] block: add missed block_acct_setup with new block device init procedure
Date: Fri, 30 Sep 2022 18:52:09 +0200 [thread overview]
Message-ID: <20220930165222.249716-6-kwolf@redhat.com> (raw)
In-Reply-To: <20220930165222.249716-1-kwolf@redhat.com>
From: "Denis V. Lunev" <den@openvz.org>
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
