To avoid conflicts with symbols defined by dependent packages all debugging symbols have been prefixed with a 'S' for SPL. Any dependent package needing to integrate with the SPL debug should include the spl-debug.h header and use the 'S' prefixed macros. They must also build with DEBUG defined.
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/
