=C2=A0
It seems to be regression test for:

commit c5c99429fa57dcf6e05203ebe3676db1ec646793
Author: Larry Woodman <lwoodman@redhat.com>
Date:=C2=A0 =C2=A0Thu Jan 24 05:49:25 2008 -0800

=C2=A0 =C2=A0 fix hugepages leak due to pagetable page sharing
=C2=A0

As far as I can tell there is no reason to allocate the memory on a
fixed address to trigger this bug but it should be easy enough to check
if the test fails on a kernel that has the two lines this patch adds
commented before and after the change it test.

That commit was m= erged in v2.6.24, it too old kernel and=C2=A0
changes a lot in the two lines, I guess it i= s not easy to test
a kernel with revert that patch.

Also can we pretty please add the commit hash to the test metadata?

+1
