Subject: [RESEND PATCH v5 2/5] mtd: ubi: use 'max_bad_blocks' to compute bad_peb_limit if available
Date: Mon, 21 Nov 2016 13:51:36 -0600 [thread overview]
Message-ID: <1479757899-6849-3-git-send-email-zach.brown@ni.com> (raw)
In-Reply-To: <1479757899-6849-1-git-send-email-zach.brown@ni.com>
From: Jeff Westfahl <jeff.westfahl@ni.com>
Use the MTD function 'max_bad_blocks' to compute the UBI bad_peb_limit,
if the function is implemented for an MTD and doesn't return an error.
