Using kmem_free() results in deducting X bytes from the memory accounting when --enable-debug is set. Unfortunately, currently the counterpart kmem_asprintf() and friends do not properly account for memory allocated, so we must do the same on free. If we don't then we end up with a negative number of lost bytes reported when the module is unloaded. A better long term fix would be to add the accounting in to the allocation side but that's a project for another day.
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.
Documentation for building, configuring, and using the SPL can be found at: http://wiki.github.com/behlendorf/spl/
