Btrfs has taken another step forward, and Linux is finally offering proper hybrid standby support. Some system administrators will be pleased about the new interfaces for the resizepart tool because they allow existing partitions to be resized without the need to reboot the system. Security improvements for soft and hard links have finally fixed a much-exploited attack vector.
Kernel trends: Outlook on 3.7
Directly following the release of Linux 3.6, the first, usually two-week long, merge window of the Linux kernel development cycle commences, during which the kernel developers incorporate the many changes for the next version of the kernel into the main development branch. Numerous changes have already been prepared for this first phase of the next development cycle.
Among the components that are ready for integration is a major revision of the Intel graphics driver that updates the code for setting screen modes. The developers are also working on a major overhaul of the Nouveau driver – although it is currently uncertain whether this code will be integrated into Linux 3.7. The same is true for the Aarch64 64-bit ARM architecture; LWN.net recently released an article about a discussion that provides an overview of the project's code development status.
As usual, the Kernel Log will summarise these and other developments in the Linux kernel field – including new point releases of the stable kernel series (3.6.y), which should, over the next few weeks, fix a few bugs that testers missed during development or which hackers could not fix in time for the release of Linux 3.6. The Kernel Log in The H Open will, as usual, be reporting on the major changes integrated into the next kernel version in a "Coming in 3.7" mini-series. A release of 3.7 in late November or early December seems likely at this point in time. A detailed summary of the major changes in 3.7 will then be published on The H Open in a Kernel Log like this one.

Linux 3.6 download
The source code is offered as tar archive compressed with Gzip, Bzip2, or XZ. The authenticity of the uncompressed tarball can be verified with a signature file that is shipped alongside it – for example, the process for Linux 3.1 would be performed with commands such as these:
[thl@thl tmp]$ wget --quiet \
[thl@thl tmp]$ xz -d linux-3.1.tar.xz
[thl@thl tmp]$ gpg --verify linux-3.1.tar.sign
gpg: Signature made Mon Oct 24 09:17:58 2011 CEST using RSA key ID 00411886
gpg: Good signature from "Linus Torvalds <firstname.lastname@example.org>"
gpg: WARNING: This key is not certified with a trusted signature!
gpg: There is no indication that the signature belongs to the owner.
Primary key fingerprint: ABAF 11C6 5A29 70B1 30AB E3C4 79BE 3E43 0041 1886
