| |
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Roman Tereshonkov <roman.tereshonkov@nokia.com>
commit 3538c56329936c78f7d356889908790006d0124c upstream.
Use block_isbad to check and skip the bad blocks reading. This will allow to get rid of the read errors if bad blocks are present initially.
