IIRC this bug used to only reproduce on rt kernels, is it still the case?
* Yes, it's a same crash.
Here besides doing correct unregister, does it also mean that even if
event_notifier_init() failed there's totally no error message anywhere?
Should we dump something when it fails? And did you check why that failed?
* In the qemu logs we see following error
VHOST_OPS_DEBUG(r, "vhost_set_mem_table failed");
goto fail_mem
After this execution likely did not reach the event_notifier_init() call, because: goto fail_mem.
* But in case it fails, no error message gets logged. Do we want to add it in this same patch?
Thank you.
