Hi Dan, Is there a canonical way to refer to a particular branch of a particular tree? >From what I observed on mailing lists people seem to say "linux-next" or "upstream tree" and that seems to mean specific things that everybody understands.

These are flattened into text format for human consumption and sent over unreliable media. > > console output: https://syzkaller.appspot.com/x/log.txt?x=10c4e63c100000 > > kernel config: https://syzkaller.appspot.com/x/.config?x=668983fd3dd1087e > > dashboard link: https://syzkaller.appspot.com/bug?extid=9c6f0f1f8e32223df9a4 > > compiler: gcc (GCC) 9.0.0 20181231 (experimental) > > syz repro: https://syzkaller.appspot.com/x/repro.syz?x=17eaba3c100000 > > C reproducer: https://syzkaller.appspot.com/x/repro.c?x=128598f6100000 > > > > regards, > dan carpenter > > > -- > You received this message because you are subscribed to the Google Groups "syzkaller-bugs" group. > To unsubscribe from this group and stop receiving emails from it, send an email to syzkaller-bugs+unsubscribe@googlegroups.com. > To view this discussion on the web visit https://groups.google.com/d/msgid/syzkaller-bugs/20200521140803.GI30374%40kadam.
