A zlib regression test has been added to verify the correct behavior of z_compress_level() and z_uncompress. The test case simply takes a 128k buffer, it compresses the buffer, it them uncompresses the buffer, and finally it compares the buffers after the transform. If the buffers match then everything is fine and no data was lost. It performs this test for all 9 zlib compression levels.
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
