Hi :

  I have quick question reg Linux 2.4.18, Ive tried to understand the code
but am pretty confused:

  In the typical malloc execution-path,  the page is added to swap and it's
pte_chain is unmapped  after which the writepage() is executed.  However I
notice that *after* the writepage(), the page->buffers is NON_NULL.

  Is this supposed to happen? I thought the writepage function flushed the
page to swap, so why are there residual buffers?

Thanks,
----
Anand.
