From 141e6ebd1b1759bd5cebf092b7216b6f1c7b4c4f Mon Sep 17 00:00:00 2001 From: Corentin Chary Date: Mon, 5 Jan 2009 14:44:11 +0100 Subject: UBI: add ioctl for map operation This patch adds ioctl for the LEB map operation (as a debugging option so far). [Re-named ioctl to make it look the same as the other one and made some minor stylistic changes.
