Libguestfs - Oct 2013 - [PATCH 0/2] pxzcat preallocation

Hello,
Here is a quick patch so that pxzcat creates sparse files without
fragmentation.  It preallocates the file, then discards extents that
weren't written.  This relies on Linux syscalls.

  Preallocate output file
  Discard unwritten ranges
