Namhyung Kim 9fdd8a875c tracing, mm: Record pfn instead of pointer to struct page ... The struct page is opaque for userspace tools, so it'd be better to save pfn in order to identify page frames. The textual output of $debugfs/tracing/trace file remains unchanged and only raw (binary) data format is changed - but thanks to libtraceevent, userspace tools which deal with the raw data (like perf and trace-cmd) can parse the format easily. So impact on the userspace will also be minimal.
