Spl's debugging and assertion macros macro used the typical do/while(0) form for if/else friendliness, however, this limits their use in contexts where a do loop is not valid; such as within another multi-statement style macro. The following macros have been converted to not use do/while(0): PANIC, ASSERT, ASSERTF, VERIFY, VERIFY3_IMPL PANIC has been converted to a wrapper around the new spl_PANIC() function. The other macros have been converted to use the "&&" operator for the branch-predicition conditional and also to use spl_PANIC(). The __ASSERT() macro was not touched. It is only used by the debugging infrastructure and that code, including this macro, will be retired when the tracepoint patches are merged.

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-...
The SPL comes with an automated test suite called SPLAT. The test suite is implemented in two parts. There is a kernel module which contains the tests and a user space utility which controls which tests are run. To run the full test suite:
$ sudo insmod ./module/splat/splat.ko
$ sudo ./cmd/splat --all
Full documentation for building, configuring, testing, and using the SPL can be found at: http://zfsonlinux.org
