Brian Behlendorf 03a783534a Fix debug object on stack warning 
When running the SPLAT tests on a kernel with CONFIG_DEBUG_OBJECTS=y
enabled the following warning is generated.

  ODEBUG: object is on stack, but not annotated
  WARNING: at lib/debugobjects.c:300 __debug_object_init+0x221/0x480()

This is caused by the test cases placing a debug object on the stack
rather than the heap.  This isn't harmful since they are small objects
but to make CONFIG_DEBUG_OBJECTS=y happy the objects have been relocated
to the heap.  This impacted taskq tests 1, 3, and 7.

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 do not want the overhead of maintaining a large patch which converts Solaris primitives to Linux primitives.

To build packages for your distribution:

$ ./configure
$ make pkg

If you are building directly from the git tree and not an officially released tarball you will need to generate the configure script. This can be done by executing the autogen.sh script after installing the GNU autotools for your distribution.

To copy the kernel code inside your kernel source tree for builtin compilation:

$ ./configure --enable-linux-builtin --with-linux=/usr/src/linux-...
$ ./copy-builtin /usr/src/linux-...

The SPL comes with an automated test suite called SPLAT. The test suite is implemented in two parts. There is a kernel module which contains the tests and a user space utility which controls which tests are run. To run the full test suite:

$ sudo insmod ./module/splat/splat.ko
$ sudo ./cmd/splat --all

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