SubjectLinux 4.8: Reported regressions as of Sunday, 2016-09-11
Hi! Here is my third regression report for Linux 4.8. It lists 10
regressions I'm aware of. 6 of them are new; 3 mentioned in the last
report sent two weeks ago got fixed; 3 got removed for other reasons
(see below).

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

Ciao, Thorsten

P.S.: Sorry for not sending a report last week, I did not find the time
as I was travelling :-/

Repo: 2016-08-30

Note: patch "ipc/shm: fix crash if CONFIG_SHMEM is not set" is going to fix this

Note: fix heading upstream

Desc: regression in re-read operation by iozone ~10%
Repo: 2016-09-02

Repo: 2016-08-21

Note: long discussion if this is considered a regression at all; mentioned it in the last report to make sure people are aware of the issue; nothing happened since then, so I assume people do not consider it a regression
