This patch series introduces /proc/pid/pagemap and /proc/kpagemap, which allow detailed run-time examination of process memory usage at a page granularity. The first several patches whip the page-walking code introduced for /proc/pid/smaps and clear_refs into a more generic form, the next couple make those interfaces optional, and the last two introduce the new interfaces, also optional. This respin adds simple, expandable headers to both pagemap and kpagemap as suggested by Nikita. I haven't moved pagewalk.c from lib/ to mm/ as suggested by Nick as I still think lib is a better fit for its automatic conditional linking. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
