There's a new release of the increasingly inaccurately named
thin-provisioning-tools:

https://github.com/jthornber/thin-provisioning-tools/releases/tag/v0.4.0

This contains tools for manipulating the dm metadata for dm-thin,
dm-cache and dm-era.

There is also an updated thinp_xml Ruby gem which can generate, parse
and emit the XML format of the above three metadata types.

https://rubygems.org/gems/thinp_xml




Changes
=======

- All tools switch to using libaio.  This gives a large performance
  boost, especially to the write focused tools like thin_restore.

- Added a progress monitor to thin_restore, cache_restore and era_restore

- Added a --quiet/-q option to *_restore to turn off the progress bar

- Removed variable hint size support from cache tools.  The kernel
  still only supports a fixed 32bit width.  This will have a side
  effect of reducing the executable sizes due to less template
  instatiation.

- Tools rolled into a single executable to save space.

- Fixed some bugs when walking bitsets (possibly effecting cache_dump
  and cache_check).
