Brian Behlendorf bf0c60c060 Add linux compatibility tests 
While the splat tests were originally designed to stress test
the Solaris primatives.  I am extending them to include some kernel
compatibility tests.  Certain linux APIs have changed frequently.
These tests ensure that added compatibility is working properly
and no unnoticed regression have slipped in.

Test 1 and 2 add basic regression tests for shrink_icache_memory
and shrink_dcache_memory.  These are simply functional tests to
ensure we can call these functions safely.  Checking for correct
behavior is more difficult since other running processes will
influence the behavior.  However, these functions are provided
by the kernel so if we can successfully call them we assume they
are working correctly.

Test 3 checks that shrinker functions are being registered and
called correctly.  As of Linux 3.0 the shrinker API has changed
four different times so I felt the need to add a trivial test
case to ensure each variant works as expected.

The Solaris Porting Layer (SPL) is a Linux kernel module which provides many of the Solaris kernel APIs. This shim layer makes it possible to run Solaris kernel code in the Linux kernel with relatively minimal modification. This can be particularly useful when you want to track upstream Solaris development closely and don’t want the overhead of maintaining a large patch which converts Solaris primitives to Linux primitives.

To build packages for your distribution:

$ ./configure
$ make pkg

Full documentation for building, configuring, and using the SPL can be found at: http://zfsonlinux.org
