Previously this check was only performed when ./configure was attempting to autodetect your kernel source directory. But we should also handle the case where --with-linux was provided and is obviously wrong. This way we catch the error before invoking make and compiling the source with an incorrect autoconf results. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #162
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
