+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.
