From eb89580e1a8388d206bf143c6c39d001095106ba Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 3 May 2010 09:04:39 +0300 Subject: UBI: introduce a new IO return code This patch introduces the %UBI_IO_BAD_HDR_READ return code for the I/O level function. We will use this code in order to distinguish between "corrupted header possibly because this is non-ubi data" and "corrupted header possibly because of real data corruption and ECC error". So far this patch does not introduce any functional change, just a preparation.
