Richard Yao 546f38433a SET_ERROR should print strings 
When debugging with tracepoints, we see string pointers:

zfs  3017 [006]  8878.728915: zfs:zfs_set__error: ffffffffa0eec3fc:3013:ffffffffa0ebcd60(): error 0x2

        636f695f637a6c00 [unknown] ([unknown])

Printing the actual strings is more convenient:

zfs  3461 [001] 10599.847692: zfs:zfs_set__error: spa.c:3013:spa_open_common(): error 0x2

        636f695f637a6c00 [unknown] ([unknown])

A few other tracepoints have strings as well, so switch to printing
the actual string values at the same time.

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
