Hi! Find below my fourth regression report for Linux 4.13. It lists 6 regressions I'm currently aware of. 1 of them is new, 5 got fixed since the last report (that was two weeks ago; didn't find time for compiling one last week; sorry). You can also find the report at http://bit.ly/lnxregrep413 where I try to update it every now and then. That didn't work to well in the past few weeks; but I'll try to update it at then end oft the week as the 4.13 release gets closer.
As always: Are you aware of any other regressions? Then please let me know. 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 P.S.: Thx to all those that CCed me on regression reports or provided other input, it makes compiling these reports a whole lot easier! == Current regressions == [x86/mm/gup] e585513b76: will-it-scale.per_thread_ops -6.9% regression Status: Asked on the list, but looks like issue gets ignored by everyone Note: I'm a bit unsure if adding this issue to this list was a good idea.

I'm considering to submit a revert as RFC to get a discussion going.
