The patch titled vfb: only enable if explicitly requested when compiled in has been removed from the -mm tree. Its filename was vfb-only-enable-if-explicitly-requested-when-compiled-in.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: vfb: only enable if explicitly requested when compiled in From: Frans Pop <elendil@xxxxxxxxx> The Kconfig help for the vfb driver says: Do NOT enable it for normal systems! To protect the innocent, it has to be enabled explicitly at boot time using the kernel option `video=vfb:'. This change lets the code match the description. Support for vfb:disable is kept for backwards compatibility; vfb:off works because it is tested at a higher level. Note: any undefined option (e.g. vfb:enable) will also enable this driver. The relevant code has been unchanged since before the migration to git (2.6.12). This patch fixes bugzilla #9310 and was the root cause behind http://lkml.org/lkml/2008/5/31/220.
