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 Changes from v2: * called bool_from_onoffauto(account_..., true) in the first patch to preserve original semantics before patch 2 Changes from v1: * set account_invalid/account_failed to true by default * pass OnOffAuto to block_acct_init() to handle double initialization (patch 1) * changed properties on BLK device to OnOffAuto Signed-off-by: Denis V.
