Hi! Find below my third regression report for Linux 4.13. It lists 11 regressions I'm currently aware of (or 10 if you count the two scsi-mq regressions discussions as one). 4 regressions are new; 3 got fixed since last weeks report (two others didn't even make it to the report, as they were quickly fixed); 1 gets removed. You can also find the report at http://bit.ly/lnxregrep413 where I try to update it every now and then.
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! P.P.S.: Sorry, I adjusted the report structure again because I added a new field that shows the date when a proper kernel developer (normally: one that is working in the affected subsystem) looked into issue. That should hopefully make it easier to spot regressions that are getting ignored or got stuck somehow. == 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.
