[PATCH] ufs: ufs_get_locked_page() race fix
As discussed earlier:
http://lkml.org/lkml/2006/6/28/136
this patch fixes such issue:
`ufs_get_locked_page' takes page from cache
after that `vmtruncate' takes page and deletes it from cache
`ufs_get_locked_page' locks page, and reports about EIO error.
Also because of find_lock_page always return valid page or NULL, we have no
need to check it if page not NULL.
