Subject: [PATCH] RHEL: Add support for QMP I/O error reason
|
|
|
9119d9 |
|
|
|
7a3408 |
RHEL-only
|
|
|
9119d9 |
|
|
|
9119d9 |
Adds support for __com.redhat_reason on I/O error events. The code will
|
|
|
9119d9 |
fallback to upstream nospace boolean if the reason is not present and
|
|
|
9119d9 |
complain if neither of these is found.
