Because spl_slab_size() was always returning -ENOSPC for caches of type KMC_OFFSLAB the cache could never be created. Additionally the slab size is rounded up to a page which is what kv_alloc() expects. The kv_alloc() code will minimally allocate a page, in the KMC_OFFSLAB case this could be reduced. The basic regression tests kmem:slab_small, kmem:slab_large, and kmem:slab_align regression were updated to test KMC_OFFSLAB.

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