The effectiveness of KSM and MADV_MERGEABLE is shown in /sys/kernel/mm/ksm/:

pages_shared     - how many shared pages are being used
pages_sharing    - how many more sites are sharing them i.e. how much saved
pages_unshared   - how many pages unique but repeatedly checked for merging
pages_volatile   - how many pages changing too fast to be placed in a tree

GITHUB_URL = Public repo on GitHub.
BITBUCKET_URL = Private repo on Bitbucket.

Given a upstream repo on GitHub in order to clone it to Bitbucket to keep 
the configuration non public (for example, to create specific ansible playbooks
with a set of roles), do this (only once!).

1. Create a new repo on Bitbucket. (BITBUCKET_URL)
2. Clone the upstream repo from Github to your local machine: git clone GITHUB_URL
3. git remote rename origin upstream BITBUCKET_URL

# Examples

# Debug syscalls for a daemon
strace -e poll,select,connect,recvfrom,sendto nc www.news.com 80

# Attach to process and sent to output.txt
strace -c -p 11084 -o output.txt

# Check permissions
strace -e open,read,access ls 2>&1 | grep your-filename

Create a playbook called deploy_role.yml:

- hosts: {{ hosts }}
  roles: {{ roles }}


And then you can do:

ansible-playbook deploy_role.yml -e hosts=somehost -e roles=somerole
