Prior to Linux 3.1 the kern_path_parent symbol was exported for use by kernel modules. As of Linux 3.1 it is now longer easily available. To handle this case the spl will now dynamically look up address of the missing symbol at module load time. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #52
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
