[This email was generated by a script. Let me know if you have any suggestions
to make it better.]
Of the currently open syzbot reports against the upstream kernel, I've manually
marked 9 of them as possibly being bugs in the sound 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 9 bugs, 1 was bisected to a commit from the following person:
Takashi Iwai <tiwai at suse.de>
If you believe a bug is no longer valid, please close the syzbot report by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 sound subsystem, please let me know,
and if possible forward the report to the correct people or mailing list.
Here are the bugs:
