I did not like the way we cleared delalloc state on a page before
getting an extra reference on it. That's one line, most of this
is dead code cleanup.

The following file(s) were checked into:
bonnie.engr.sgi.com:/isms/slinx/2.4.x-xfs
Modid: 2.4.x-xfs:slinx:87227a
linux/include/linux/page_buf.h - 1.73
- Changed prototype for _pagebuf_lookup_pages(), remove some unused
definitions.
linux/fs/pagebuf/page_buf.c - 1.52
- Remove unused code from the _pagebuf_lookup_pages() function, it had
the capability to populate partial pagebufs, this is not used, and is
somewhat obscure code.
linux/fs/pagebuf/page_buf_io.c - 1.50
- In the read_full_page path always attach buffer heads to pages, this
appears to help. change calls to _pagebuf_lookup_pages to remove
deleted
parameters, use page_cache calls instead of direct page calls, and
in the delalloc conversion path, take a reference on the page being
converted before removing the delalloc flag.
