O-Subject: [RHEL-8.0 qemu-kvm PATCH 14/15] block-backend: Set werror/rerror defaults in blk_new()

|
|
Currently, the default values for werror and rerror have to be set
|
|
explicitly with blk_set_on_error() by the callers of blk_new(). The only
|
|
caller actually doing this is blockdev_init(), which is called for
|
|
BlockBackends created using -drive.
|
|
|
|
In particular, anonymous BlockBackends created with
|
|
-device ...,drive=<node-name> didn't get the correct default set and
|
|
instead defaulted to the integer value 0 (= BLOCKDEV_ON_ERROR_REPORT).
|
|
This is the intended default for rerror anyway, but the default for
|
|
werror should be BLOCKDEV_ON_ERROR_ENOSPC.
|
|
|
|
Set the defaults in blk_new() instead so that they apply no matter what
|
|
way the BlockBackend was created.
