| H A D | transaction.c | bf0da8c1 Fri Nov 04 11:29:37 CDT 2011 Chris Mason <chris.mason@oracle.com> Btrfs: ClearPageError during writepage and clean_tree_block
Failure testing was tripping up over stale PageError bits in
metadata pages. If we have an io error on a block, and later on
end up reusing it, nobody ever clears PageError on those pages.
During commit, we'll find PageError and think we had trouble writing
the block, which will lead to aborts and other problems.
This changes clean_tree_block and the btrfs writepage code to
clear the PageError bit. In both cases we're either completely
done with the page or the page has good stuff and the error bit
is no longer valid.
