[Libguestfs] [PATCH nbdkit v2 0/3] Rewrite xz plugin as a filter.

[Richard W.M. Jones]

v2:

 - Fixes a number of bugs in corner cases.

 - Uses a 1M block size to fetch from the underlying plugin.  This
   improves performance considerably.

I also tested this much more thoroughly and can't find any more bugs.

Rich.
