cxl_memdev_sanitize could fail for some reasons(lack of hardware support,
device busy etc)
I'd like to log more details for the failure, something like:
+ if (rc) {
+ log_err(&ml, "one or more failures, last failure: %s\n",
+ strerror(-rc));
+ }
Otherwise,
I tested it with QEMU and CXL_TEST, it worked
