However, just to clarify, the 17 syzbot bugs I assigned to TLS are in addition to the 30 I assigned to BPF (https://lore.kernel.org/lkml/20190624050114.GA30702@sol.localdomain/). (Well, since I sent that it's actually up to 35 now.) I do expect most of these are duplicates, so when you are fixing the bugs, it would be really helpful (for everyone, including you in the future :-) ) if you would include the corresponding Reported-by syzbot line for *every* syzbot report you think is addressed, so they get closed. - Eric
