[f2fs-dev] [PATCH] f2fs: remove unnecessary TestClearPageError whenwait pages writeback

From: Chao Yu
Date: Sun Nov 03 2013 - 21:30:45 EST


In wait_on_node_pages_writeback we will test and clear error flag for all pages in radix tree, but not necessary.
So we only do this for pages belong to the specified inode.
