The __get_free_pages() function must be used in place of kmalloc() to ensure the __GFP_COMP is strictly honored. This is due to kmalloc() being layered on the generic Linux slab caches. It wasn't until recently that all caches were created using __GFP_COMP. This means that it is possible for a kmalloc() which passed the __GFP_COMP flag to be returned a non-compound allocation.

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
