What is the ETA on actually fixing the bug(s)? There are now like 20 syzbot reports for seemingly the same bug, since it's apparently causing massive memory corruption; and this is wasting a lot of other kernel developers' time. This has been going on for over a month; any reason why it's taking so long to fix? Also, have you written a regression test for this bug so it doesn't happen again? - Eric
