Hmmm. I might be a little too nitpicky, but I hate having the same
partial condition duplicated if possible. Why not:
if (rc == -EAGAIN) {
if (wbc->sync_mode == WB_SYNC_ALL)
goto retry_write;
redirty_page_for_writepage(wbc, page);
} else if (rc) {
SetPageError(page);
mapping_set_error(page->mapping, rc);
} else {
SetPageUptodate(page);
}
Otherwise this looks fine to me:
