Subject: Reminder: 5 open syzbot bugs in "net/smc" subsystem

[This email was generated by a script.  Let me know if you have any suggestions
to make it better, or if you want it re-generated with the latest status.]

Of the currently open syzbot reports against the upstream kernel, I've manually
marked 5 of them as possibly being bugs in the "net/smc" subsystem.  I've listed
these reports below, sorted by an algorithm that tries to list first the reports
most likely to be still valid, important, and actionable.

Of these 5 bugs, 4 were seen in mainline in the last week.

Of these 5 bugs, 1 was bisected to a commit from the following person:

	Ursula Braun <ubraun@...ux.ibm.com>

If you believe a bug is no longer valid, please close the syzbot report by
sending a '#syz fix', '#syz dup', or '#syz invalid' command in reply to the
original thread, as explained at https://goo.gl/tpsmEJ#status

If you believe I misattributed a bug to the "net/smc" subsystem, please let me
know, and if possible forward the report to the correct people or mailing list.

Here are the bugs:

syzbot has bisected this bug, but I think the bisection result is incorrect.
