This library provides a variety of compatibility functions for ZFS on Linux:
 * libspl: The Solaris Porting Layer userland library, which provides APIs
   that make it possible to run Solaris user code in a Linux environment
   with relatively minimal modification.
 * libavl: The Adelson-Velskii Landis balanced binary tree manipulation
   library.
 * libefi: The Extensible Firmware Interface library for GUID disk
   partitioning.
