[PATCH] fix race in pagevec_strip?
[PATCH] fix race in pagevec_strip?

We can call try_to_release_page() with PagePrivate off and a valid
page->mapping This may cause all sorts of trouble for the filesystem
*_releasepage() handlers.  XFS bombs out in that case.

Lock the page before checking for page private.
