Best tests to measure Kernel Performance
by Victor Rodriguez Dec. 3, 2015

Dec. 3, 2015

Hi Despite the fact that this is not a well formulated question. I wonder what tests could be a good subset to measure the performance of the kernel . I have some approaches like phoronix does here : http://www.phoronix.com/scan.php?page=article&item=linux-41-byt&num=1 I am sure postmark/ John the ripper/ Apache are good candidates but I want to ask the community if there is some specific test that you recommend Thanks a lot for the help Regards Victor Rodriguez

Figuring out the right patch receivers
by Sinclair Yeh Dec. 2, 2015

Dec. 2, 2015

Hi, For the first time, I sent out a patch series that touched multiple subsystems. I used "get_maintainer.pl" to figure out who all the maintainers are and decided to send the entire series to x86(a)kernel.org" and Cc "linux-kernel(a)vger.kernel.org" I also Cc'ed individual patches to (what I thought were) the appropriate maintainers. One of the maintainers, GregKH, said I probably should have CC'ed him on the entire series, but get_maintainer.pl listed him as a "supporter" for only a subset of the patches. Can someone tell me where I went wrong in my thought process so I can get it right the next time? thanks, Sinclair PS. Mentioning GregKH rather than "a maintainer" only because I know he maintains kernel-stable so maybe he's got a more expanded role. Since the series was not for kernel-stable, I thought following get_maintainer.pl is the right approach.

objdiff usage
by Bogicevic Sasa Dec. 2, 2015

Hi all, I am looking for a guidance on ./scripts/objdiff usage, cant seem to find a goot example of the scenario where you for example make a bunch of changes (code style issues) in one folder and need to check if that│changes don't change the object file. That can speed up code cleaning quite a bi but all I found online are patches related to objdiff. │ Thanks,Sasa
