In certain situations kernel tracking seems to be getting confused and incorrectly reporting the slot of a contact. On example is when the user does a three finger click or tap and then places two fingers on the touchpad in the same area. The kernel tracking code seems to continue to think that there are three contacts on the touchpad and incorrectly alternates the slot of one of the contacts. The result that is the input subsystem reports a stream of button press and release events as the reported slot changes. Kernel tracking was originally enabled to prevent cursor jumps, but it is unclear how much of an issue kernel jumps actually are. This patch simply disabled kernel tracking for now.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
