Add script for builtin module building.
This commit introduces a "copy-builtin" script designed to prepare a kernel source tree for building ZFS as a builtin module. The script makes a full copy of all needed files, thus making the kernel source tree fully independent of the zfs 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 zfs source package. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #851

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-...
