BTRFS deduplication

External tool to find duplicated extens available https://github.com/markfasheh/duperemove

Simply do 'make' and 'make install' Following binaries will be installed:

• btrfs-extent-same
• csum-test
• duperemove
• hashstats
• show-shared-extents

Recursively find duplicates in <dir>

duperemove -r <dir>

The same as above, but make real deduplication (on BTRFS only)

duperemove -rd <dir>

Increase deduplication chance by reducing block size to 4k:

duperemove -b 4k -rd <dir>

This deduplication works nice, it can find some shared parts inside Maildir.
