Hi Steven, Dhaval,

Acknowledged.

Then smaller topic that would benefit from discussion are:

the main one being:

1. syzbot: developer process; unfixed bugs; bug triage; what's
working? what's not? why? how can we make more parts work? collecting
feedback

2. how to increase test coverage/find more bugs, in particular:
 - adding manual spot KASAN/KMSAN checks into kernel codebase
 - stubbing hardware/external inputs to kernel for testing
 - description of kernel interfaces (again)

3. dealing with kernel console output mess
 - intermixed/split lines
 - understand when/how kernel crashed
 - and where is that message
 - crash identity
