OK. The patch was not really written just by picking a random proc entry. I
have used this extensively
with success in occasions related to low memory situations. Like debugging
crashes (or forced crashes)
where OOM killer has triggered, and similarly to debug the the migration of
pages (especially with the contiguous
memory allocator recently added to Linux). In such situations we have to
know 'where our pages really are".
But I understand, it was helpful to me does not mean that it is for
everyone.
