    nothing happens!) And if you love to see tons of detailed statstics
    changing dynamically try running the following bash script in a big window
    with "watch -d":

      "31 btrfs"
      -> included latest btrfs changes from 2.6.37 to 2.6.38-rc4 (as of February 15th) (commit: c26a920373a983b52223eed5a13b97404d8b4158 (as of February 15th) in http://git.eu.kernel.org/?p=linux/ke....git;a=summary)

      2 [PATCH] fix (latent?) memory corruption in btrfs_encode_fh()
      you can try to use btrfs with zcache but most likely a (yet to be fixed) BUG will be triggered: http://forums.gentoo.org/viewtopic-p...9.html#6571799

      upstream has been notified - no solution or patch to fix it has been posted yet

      - more efficiency in CFS (cpu scheduler): removed cruft from HT scheduler
      - more memory efficiency: fixed memory leaks in zcache, filesystem, and "fs: remove 8 bytes of padding from block_device on 64bit builds"
      - latest btrfs from February 15th

      kudos to all devs making this possible !

          linux-phc only seems to support undervolting - no over- or underclocking so far

          so you still need to set those things in your Bios or EFI
