Issue #1775

Porting notes:

1. There is no clear way to distinguish between a failure when we
   tried to unmount the snapdir of a zvol (which does not exist)
   and the failure when we try to unmount a snapdir of a dataset,
   so the changes to zfs_unmount_snap() were dropped in favor of
   an altered Linux function that unconditionally returns 0.

Native ZFS for Linux!

ZFS is an advanced file system and volume manager which was originally developed for Solaris and is now maintained by the Illumos community.

ZFS on Linux, which is also known as ZoL, is currently feature complete. It includes fully functional and stable SPA, DMU, ZVOL, and ZPL layers.

Full documentation for installing ZoL on your favorite Linux distribution can be found at: http://zfsonlinux.org
