Hi, Minchan. This is a set of commits based on our discussion on your submission [1]. First 2 implement minor suggestions just for you to not forget to take them into account. uio.h inclusion was needed for me to be able to compile your series successfully. Also please note I had to enable "Transparent Hugepage Support" as well as "Enable idle page tracking" options, otherwise the build failed. I guess this can be addressed by you better since the errors are introduced with MADV_COLD introduction. Last 2 commits are the actual KSM hints enablement. The first one implements additional check for the case where the mmap_sem is taken for write, and the second one just allows KSM hints to be used by the remote interface. I'm not Cc'ing else anyone except two mailing lists to not distract people unnecessarily. If you are fine with this addition, please use it for your next iteration of process_madvise(), and then you'll Cc all the people needed. Thanks.
