This reverts commit b109eec6f4332bd517e2f41e207037c4b9065094. If I'm filling up a filesystem with this sort of command: $ dd if=/dev/urandom of=/mnt/cephfs/fillfile bs=2M oflag=sync ...then I'll eventually get back EIO on a write. Further calls will give us ENOSPC. I'm not sure what prompted this change, but I don't think it's what we want to do. If writepages failed, we will have already set the mapping error appropriately, and that's what gets reported by fsync() or close(). __filemap_fdatawait_range however, does this: wait_on_page_writeback(page); if (TestClearPageError(page)) ret = -EIO; ...and that -EIO ends up trumping the mapping's error if one exists. When writepages fails, we only want to set the error in the mapping, and not flag the individual pages.
