Subject: [PATCH 2/2] ras-page-isolation: page which is PAGE_OFFLINE_FAILED can
|
|
be offlined again
|
|
|
|
OS may fail to offline page at the previous time. After some time,
|
|
this page's state changed, and the page can be offlined by OS.
|
|
At this time, Correctable errors on this page reached the threshold.
|
|
Rasdaemon should trigger to offline this page again.
