The patch titled input: allow certain EV_ABS events to bypass all filtering has been removed from the -mm tree. Its filename was input-allow-certain-ev_abs-events-to-bypass-all-filtering.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: input: allow certain EV_ABS events to bypass all filtering From: Henrik Rydberg <rydberg@xxxxxxxxxxx> With the upcoming multi-touch interface as an example, there is a need to make certain that all reported events actually get passed to the event handler. This patch equips the input core with the ability to bypass all filtering for certain EV_ABS events.
