On 32-bit, we can't use %lu to print a size_t variable and gcc warns us
about it.  Shame it doesn't warn about it on 64-bit.

Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
Fixes: cc86e0c2f306 (radix tree test suite: add support for slab bulk APIs)
Signed-off-by: Liam R. Howlett <Liam.Howlett@oracle.com>

Note that this requires the patch to fix the headers [1] for the testing
to build.  Unfortunately, that has not landed, but the patches do not
conflict so we should push this upstream anyways.

Sorry, This should not have been 'in-reply-to' the previous older patch
set.  Let me know if you want me to resend.

Thanks,
Liam
