waiting on writepage operation

Noticed that filemap_write_page has a wait parameter that is being unused. When called from the swapout path, the calling routine does not intend the operation to block ... so it calls filemap_write_page with wait = 0. However, the writepage operation of the address space does not support the notion of waiting. Is there a reason to hope that the wait argument might become part of writepage()? It will be great to work out a dead-lock situation in XFS by simply bailing out of the writepage if it was called with wait = 0.

Thanks for any suggestions,
