Hello Alison,

I wanted to ask about this scenario.
Is my understanding correct that this fix is needed for cases without Soft Reserve and:
1) CXL memory is installed in the server (no hotplug) and OS is started
2) CXL memory is hot-plugged after the OS starts
3) Tests with cxl-test driver

In such case either the admin fails to manually create region via cxl cli (if there
was no auto-regions) or regions fails to be created automatically during driver probe

Is this correct?

Best regards,
Tomasz
