S3 and S4 fix for 2.5.x XFS

S3 and S4 fix for 2.5.x XFS

[Karol Kozimor]

Hi,
Eric Sandeen <sandeen-sJ/iWh9BUns@public.gmane.org> wrote a fix for 2.5.x page_buf.c that is
similar to that for 2.4.x and allows for pagebufd to enter refrigerator
correctly. It seems to work fine for me (2.5.61), though I also suffer 
from some mysterious XFS problems that need further inquiring.

Everyone using XFS and S3 or S4 is highly encouraged to test this patch on
a 2.5.x kernel. The patch is below:

Patch looks good; submit it to trivial if it looks like it works...
