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,
