Linux 4.9: Reported regressions as of Sunday, 2016-11-20

Mon Nov 21 02:09:51 AEDT 2016

Hi! Here is my fourth regression report for Linux 4.9. It lists 10
regressions I'm aware of. 6 of them are new; 11 got fixed (wow!)
since the last report -- that was two weeks ago, because I 
didn't find any spare time to compile a report last Sunday :-/

As always: Are you aware of any other regressions? Then please let me
know (simply CC regressions at leemhuis.info). And please tell me if there
is anything in the report that shouldn't be there.

Ciao, Thorsten
