Look, the crash utility could effectively mimic every file in the
/proc filesystem. But that doesn't mean that it should -- somewhere
that has to be a line to be drawn.
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.
Can you make it an extension module? I'll host it on the extensions
web page, and if there becomes a consensus where people find that they
can't live without it, then it can be reconsidered for the base
crash utility.
Sure I will do this.
