Brian Behlendorf d148e95156 Fix negative zio->io_error which must be positive. 
All the upper layers of zfs expect zio->io_error to be positive.  I was
careful but I missed one instance in vdev_disk_physio_completion() which
could return a negative error.  To ensure all cases are always caught I
had additionally added an ASSERT() to check this before zio_interpret().

Finally, as a debugging aid when zfs is build with --enable-debug all
errors from the backing block devices will be reported to the console
with an error message like this:

	ZFS: zio error=5 type=1 offset=4217856 size=8192 flags=60440

README.markdown

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!

$ ./configure
$ make pkg
