From 83cef708c606f46a2b527af025acb3d24555f0c4 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Fri, 3 Jun 2011 13:45:09 +0300 Subject: UBIFS: introduce more I/O helpers Introduce the following I/O helper functions: 'ubifs_leb_read()', 'ubifs_leb_write()', 'ubifs_leb_change()', 'ubifs_leb_unmap()', 'ubifs_leb_map()', 'ubifs_is_mapped(). The idea is to wrap all UBI I/O functions in order to encapsulate various assertions and error path handling (error message, stack dump, switching to R/O mode). And there are some other benefits of this which will be used in the following patches. This patch does not switch whole UBIFS to use these functions yet.
