Benjamin Tissoires d9ca1c990a Input: reserve 2 events code because of HID ... Prior to commit 190d7f02ce ("HID: input: do not increment usages when a duplicate is found") from the v4.18 kernel, HID used to shift the event codes if a duplicate usage was found. This ended up in a situation where a device would export a ton of ABS_MISC+n event codes, or a ton of REL_MISC+n event codes. This is now fixed, however userspace needs to detect those situation. Fortunately, ABS_MT_SLOT-1 (ABS_MISC+6) was never assigned a code, and so libinput can detect fake multitouch devices from genuine ones by checking if ABS_MT_SLOT-1 is set. Now that we have REL_WHEEL_HI_RES, libinput won't be able to differentiate true high res mice from some other device in a pre-v4.18 kernel. Set in stone that the ABS_MISC+6 and REL_MISC+1 are reserved and should not be used so userspace can properly work around those old kernels.
