Hi, this is your Linux kernel regression tracker speaking.

Once again. The fix sadly didn't link to the mail with the report on the
list, as it should (see https://git.kernel.org/linus/1f57bd42b77c ),
otherwise this message wouldn't be needed. But whatever, for the record
& regzbot:

A fix was committed here:

https://kernel.googlesource.com/pub/scm/linux/kernel/git/tnguy/net-queue/+/de98e3651464acb08a5bba6df9ad323c7e9cdc33

Not yet in next and the commit-id is likely to different later, but I
ignore that for now and tell regzbot about it nevertheless:

#regzbot fixed-by: de98e3651464acb08a5bba6df9ad323c7e9cdc33

Ciao, Thorsten
