two questions about MM in kernel2.4

[jean <nomkchina@yahoo.com>]

Hi:

two questions when I was reading the code.
1. for pages that a process obtain after a write
anonymous fault, what are the mapping and index value?
are they null values? do those pages belong to page
cache? or swap cache? (not untill they are swapped
out, right?) They're in lru_cache, but not in any
inode queue, right?

2. Where can I find code for:
vma->vm_ops->nopage
implementation? 
does this ultimately go to brw_page( )? if not cached?

thanks

jean
