As Linus Torvalds pointed out in the 3.15-rc3 announcement, it's been a fairly straightforward week for being midway through the 3.15 kernel development cycle. There isn't any major pull requests coming in late to fix any big breaks, etc. Linus wrote, "So far, no big scares, and rc3 is appropriately smaller than rc2 was, so we're following the right trajectory here. The statistics look fairly normal too, with half drivers (input, usb, gpu, acpi, regulator..) and a third arch updates (much of it again arm dts files, but other arm and some um updates too). The rest is misc, but mainly concentrated in filesystem updates (btrfs and ext4)."
While things are calm now, the Linux 3.15 merge window a few weeks ago was very busy. If you are not yet familiar with the Linux 3.15 kernel features, be sure to read about the many great Linux 3.15 additions.
Now that things are coming down within the kernel tree and that all early fallout to the Linux 3.15 kernel have been addressed, this week I should be able to proceed with my usual benchmarking of the EXT4/Btrfs/XFS/F2FS file-systems, Intel/Radeon/Nouveau DRM graphics tests, and other Intel/AMD/ARM CPU benchmarks... Early on in Linux 3.15 I hit some file-system fall-out and Radeon DRM graphics issues, but it looks like Linux 3.15-rc3 might be in good shape for beginning to run a horde of Linux 3.15 benchmarks for publication on Phoronix.com in the days ahead using the Phoronix Test Suite benchmarking software.
