This commit introduces a "copy-builtin" script designed to prepare a kernel source tree for building SPL as a builtin module. The script makes a full copy of all needed files, thus making the kernel source tree fully independent of the spl source package. To achieve that, some compilation flags (-include, -I) have been moved to module/Makefile. This Makefile is only used when compiling external modules; when compiling builtin modules, a Kbuild file generated by the configure-builtin script is used instead. This makes sure Makefiles inside the kernel source tree does not contain references to the spl source package. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue zfsonlinux/zfs#851

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-...
|
||
|
||
