This library provides a variety of glue functions for openzfs on linux:
* libspl: the solaris porting layer 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.
* libshare: nfs and smb service integration for openzfs.
