-Subject: [PATCH v3 libinput] touchpad: serial synaptics need to fake new touches on TRIPLETAP
-
-On the 4.1 kernels synaptics pretends to have 3 slots (the serial fw only does
-2). This was added to avoid cursor jumps but has since been reverted for 4.2
-(kernel commit dbf3c37086, 4.1.3 is still buggy). In some cases a TRIPLETAP
-may be triggered without slot 2 ever activating.
-
-While there are still those kernels out there, work around this bug by opening
-a new touch point where none exists if the fake finger count exceeds the slot
-count.

-Changes to v2:
-- split out the handling instead of having a tmp state variable, see Hans'
-  comments from v2
-
-Mainly sending this to the list again so I have a link to point people to.
-If you're on 4.1.x add this patch to your distribution package.
