From c39d6a0ea57d57b53bd7fb8933874e1640e47888 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Thu, 14 Mar 2013 05:32:50 +0000 Subject: nand: Extend nand_(read|write)_skip_bad with *actual and limit parameters We make these two functions take a size_t pointer to how much space was used on NAND to read or write the buffer (when reads/writes happen) so that bad blocks can be accounted for. We also make them take an loff_t limit on how much data can be read or written. This means that we can now catch the case of when writing to a partition would exceed the partition size due to bad blocks. To do this we also need to make check_skip_len count not just complete blocks used but partial ones as well. All callers of nand_(read|write)_skip_bad are adjusted to call these with the most sensible limits available. The changes were started by Pantelis and finished by Tom.
