The patch titled vt: do not update when the console is blanked has been removed from the -mm tree. Its filename was vt-do-not-update-when-the-console-is-blanked.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: vt: do not update when the console is blanked From: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx> vt.c DO_UPDATE macro checks if the console is visible but doesn't check if the console is blanked. In fact updating fbcon while the console is blanked is not only unnecessary but can even cause screen corruption. Therefore I am adding a simple check on console_blanked in DO_UPDATE.
