Subject: Reminder: 3 open syzbot bugs in "net/rxrpc" 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 3 of them as possibly being bugs in the "net/rxrpc" 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 3 bugs, 1 was seen in mainline in the last week.

Of these 3 bugs, 2 were bisected to commits from the following person:

	David Howells <dhowells@...hat.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If you believe a bug is no longer valid, please close the syzbot report by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/rxrpc" subsystem, please let me
know, and if possible forward the report to the correct people or mailing list.

Here are the bugs:
