[patch-2.4.0-test9-pre1] mm/filemap.c

[Bill Wendling]

Hi Linus,
     
Here's a resubmitted small optimization for the mm/filemap.c file.
     
        - The `curr = curr->next;' statement doesn't need to be executed
          if the repeat is taken. I used the list_for_each() macro to
          accomodate this better.
     
Share and enjoy!
