Currently, when building a test case, we're compiling an entire Linux module from beginning to end. This includes the MODPOST stage, which generates a "conftest.mod.c" file with some boilerplate module declaration code. This poses a problem when configuring for built-in on kernels which have loadable module support disabled. In this case conftest.mod.c is referencing disabled code, resulting in a compilation failure, thus breaking the tests. This patch fixes the issue by faking the modpost stage when the --enable-linux-builtin option is provided. It does so by forcing the modpost command to be /bin/true, and using an empty conftest.mod.c file. The test module still compiles fine, although the result isn't loadable, but we don't really care at this point. Note it is important to preserve the modpost stage when building out of tree. This allows for the posibility of configure checks to leverage this phase to identify GPL-only symbols.

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.
To build packages for your distribution:
$ ./configure
$ make pkg
Full documentation for building, configuring, and using the SPL can be found at: http://zfsonlinux.org
