Bug#558200: closed by maximilian attems <max@stro.at> (Re: Bug#558200: linux-image-2.6.32-rc8-amd64: Please, enable CONFIG_KSM in 2.6.32)



  Hi,

  Are you sure you saw I'm talking about KSM (Kernel SamePage Merging) and
*not* about KMS (Kernel Mode Setting) ? If yes, sorry for my request and
this mail. But I've not see anything about KSM and the Debian Linux Kernel.
I will retry google and the archives of debian-devel for now.
  If you made a mistake, please reopen the bug. If not, then sorry again.
I will recheck the documentation.

  Regards,
    Vincent
