Speaking only for me, and all that. I use it. It's actually pretty handy sometimes, because it lets me peek at task structures et cetera from userspace; so when I have a problem with the kernel accessing the wrong memory, I can go figure out what it's actually looking at. This is a sort of poor-man's-kgdb. I don't think there's much need for /proc/kcore if you have a working kgdb, which I'd still like to see cleaned up and integrated. -- Daniel Jacobowitz MontaVista Software Debian GNU/Linux Developer - 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/
