Subject: [PATCH 0/2] allow scrubbing (erasing of bad blocks)
Date: Thu, 13 Dec 2012 17:18:20 +0100 [thread overview]
Message-ID: <1355415502-30673-1-git-send-email-w.sang@pengutronix.de> (raw)
This patch series first adds a flag to mtd devices which disables special
treatment for bad blocks. That means, they are handled like every other good
block. The second one then adds a scrub command which is basically a simple
erase, only that bad blocks are treated like good blocks and are trying to be
erased (which may succeed or not). This is really *not recommended*, except for
certain development use cases!
