Maybe we should use the /proc/pid/pagemap and /proc/kpageflags files? These files let a userspace process find out which physical frame each virtual page is mapped to and to get the properties of each page frame including the page size. The disadvantage of this method is, that it applicable on kernel >= 2.6.25, since this interface is supported starting from the kernel 2.6.25. -Alex -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
