I'd be using it in procps for the pmap command if it were not so horribly nasty. I may eventually get around to using it, but maybe it's just too gross to tolerate. That mess should never have slipped into the kernel. Just take a look at /proc/self/smaps some time. Wow.
A month or two ago I supplied a patch to replace smaps with something sanely parsable. I was essentially told that we already have this lovely smaps dungheap that I should just use, but a couple people were eager to see the patch go in.
Anyway, I need smaps stuff plus info about locked memory and page sizes. Solaris provides this. People seem to like it. I guess it's for performance tuning of app code or maybe for scalibility predictions. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
