Subject: [patch 10/16] give swapper_space a set_page_dirty a_op
Date: Sat, 01 Jun 2002 01:42:48 -0700 [thread overview]
Message-ID: <3CF88908.179B10BF@zip.com.au> (raw)
Give swapper_space a ->set_page_dirty() address_space_operation.
So swapcache pages do not need special-casing in
set_page_dirty_buffers().
