From 8471bb73ba10ed6788b4f1e9b8a0f9dc6bdb05b5 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Wed, 21 May 2014 19:06:12 -0300 Subject: mtd: Introduce mtd_block_isreserved() In addition to mtd_block_isbad(), which checks if a block is bad or reserved, it's needed to check if a block is reserved only (but not bad). This commit adds an MTD interface for it, in a similar fashion to mtd_block_isbad(). While here, fix mtd_block_isbad() so the out-of-bounds checking is done before the callback check.
