Kernel 2.6.1 Released

jnf writes "And so he said it is released, and then jumped on a plane to Australia. Linus announced the release of 2.6.1 a few minutes ago, fixes include AGPGART, a fork() bugfix, and misc changes to XFS, and those are just the patches applied since v2.6.1-rc3.

      That's not exactly fair. Although installing a kernel independently of a distro isn't easy, program installation in general is far, far easier than it is in MS Windows. In debian, you just type "apt-get programname". In Mandrake, you type "urpmi programname".

      In Windows, you open your web browser, go to download.com, type "programname" into the search field, click on the most likely link to the program from the search results, click on the "Download Now" link, click on the closest mirror, wait a few seconds, tell the app to "Run" instead of "Save", pray that the app is safe for your system (in the above apt-get and urpmi examples, programs are generally added into the installable app databases only after they make sure that the programs are reasonably secure and reliable), wait for the graphical installer to come up, click next, select the program components to install in one of several different ways (checkboxes, checkboxes in a scrollview, that tree-based Office2k method with the little dropdown buttons, etc..), verify the install location, click Finish, then delete the stupid excess shortcuts placed on the desktop, the shortcut bar, above the "Programs" entry in the Start menu, etc...

      Then you agree to a surprisingly restrictive and needlessly redundant ("you agree to not do the following already illegal things...") license agreement. Then, maybe, it'll make you reboot.

ATA as a whole could be implemented as part of this, the drivers would just say that your ATA drive is a SCSI drive, on an ATA bus, with a command set capable of features X,Y, and Z. It would make it a lot easier to implement TCQ and other stuff on ATA drives, and pre-ordered queing on dirty write buffers for slower serial devices.
