Install the common spl kernel development headers under /usr/src/spl-<version>/ rather than in a kernel specific directory. The kernel specific build products such as spl_config.h and Modules.symvers are left installed under /usr/src/spl-<version>/<kernel>. This was done to be consistent with where dkms expects kernel module source to be packaged. It also allows for a common spl-kmod-devel package which includes the headers, and per-kernel spl-kmod-devel-<kernel> packages. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
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
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-...
Full documentation for building, configuring, and using the SPL can be found at: http://zfsonlinux.org
