Whoops, I momentarilly forgot I had explicitly set these as CC options so dependent packages which need to include spl_config.h would not end up having these defined which can result in accidentally hanging debug enabled at best, or a build failure at worst.
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/
