[Bug tapsets/4519] New: nfs.stp nfs.aop.readpage uses field "index" which isn't available in linux 2.6.22-rc1

["wcohen at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

In newer version of the kernel 2.6.22-rc1 the "struct page" doesn't have the
index field. This is triggered by the lket test. However, the following one
liner will also demontrate the problem:

stap -v -e '  probe nfs.aop.readpage { printf("%d\n", page_index) }'

Output from testsuite:
