Linux 4.14: Reported regressions as of Sunday, 2017-10-01

[Thorsten Leemhuis]

Hi! Find below my first regression report for Linux 4.14. It lists 4
regressions I'm currently aware of (two of the reports are my own). I
skimmed LKML, bugzilla.kernel.org, but those were all I found that
looked worthy. And nobody pointed me to any regressions directly. Sigh.
Either we are doing really well this cycle or nobody wants his
regression tracked...

As always: Are you aware of any other regressions? Then please let me
know by mail (a simple bounce in my direction is enough!). For details
see http://bit.ly/lnxregtrackid And please tell me if there is anything
in the report that shouldn't be there.

Ciao, Thorsten
