I'm trying to learn about docker and the overlayFS, as suggest by the official website, I installed the last kernel: 



4.8.11-1.el7.elrepo.x86_64


and as suggest by them to ensure that overlay is good to go, I used:



 $ lsmod | grep overlay


But no success, it is because I don't have any FS or directory that is mounted with overlay, or should I do something else, like installing or loading the overlay kernel module? If so, can you suggest to me any tutorial to do so



For information I'm on: 



CentOS Linux release 7.2.1511 (Core)





centos mount docker overlayfs

          enable the kernel module with




          modprobe overlay




          alternatively add overlay to systemd :




          echo "overlay" > /etc/modules-load.d/overlay.conf




          and restart

          • I also modify /lib/systemd/system/docker.service by adding in [Service] ExecStart=/usr/bin/dockerd --storage-driver=overlay2 , that means whenever i start/reboot docker it will use overlay2 as storage driver

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
