I am not certain it has always really found the bugs it hits. My experience tends towards a bug report with too little information in the Oops to guess what went wrong, that I can not reproduce the issue locally, that the no can reproduce, that was produced on a weird tree, and with a reporter telling you they are only interested in testing fixes. Which is a long way of saying if the UI issues are bad enough the issue can not be identified in the code I am not certain we have actually found a bug. So while I can see lots of potential in syzbot. I can't say if the it is greater potential to get bugs fixed or to annoy developers with complaints they can't do anything about. Eric
