Kernel 4.7 added the option to trim the unused exported symbols. In my testing this showed to be problematic since the PDE_DATA function was considered unused and as such was trimmed. This in turn caused the respective test during spl's configure stage to falsely detect that PDE_DATA is not defined, which in turn caused build failures later. Handle this situation by adding detection whether CONFIG_TRIM_UNUSED_KSYMS is enabled and refuse to build against a kernel which has it enabled Signed-off-by: Nikolay Borisov <n.borisov.lkml@gmail.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #565 |

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
