Well, I think that covers everything interesting I came across over the past two weeks of the Linux 4.5 merge window. If I missed anything else interesting, feel free to point it out via the forums. If you like all the work invested in Phoronix with our open-source/Linux news coverage and daily Linux hardware performance benchmarks, consider subscribing to Phoronix Premium by taking part in our special deal ending at the end of today that helps provide the resources for all of our continued testing and work.

Over on continue to be benchmarks of the latest Linux kernel Git code done on a daily basis from Fedora and Ubuntu. In the days/weeks ahead will be all of our other Linux 4.5 based testing in different articles on Phoronix. In case you missed it, this week I also posted Linux 3.5 through Linux 4.4 kernel benchmarks; I preserved that system in its same state so in the next few days will extend it to include Linux 4.5-rc1.
