Dear Mel Gorman,
I found one problem in MMTests0.01/fraganalysis/Makefile
When I did "make install" here, I got the following error:
install: cannot stat `record-buddyinfo': No such file or directory
make: *** [install-script] Error 1
I think the following line in makefile need to be corrected:
#####INSTALL_SCRIPT = pagealloc-extfrag show-buddyinfo slab-intfrag record-buddyinfo

INSTALL_SCRIPT = pagealloc-extfrag show-buddyinfo slab-intfrag record-extfrag
I corrected this and it works now.

No, that particular script was not included as it needs a kernel patch
to be really useful and depends on parts of VM Regress that were very
ugly. As I've said before, I generally use unusable free space index
and fragmentation index if I'm trying to graph fragmentation-related
information. To record it, I use the "extfrag" monitor in monitors/
. It uses other helpers of which fraganalysis/show-buddyinfo is the
most important as it is the one that can read either /proc/buddyinfo
or use /proc/kpagefrags to build a more accurate picture.
