Support in-tree builtin module building.
These commits add support for compiling the ZFS module as a built-in
kernel module by copying the module code into the kernel source tree.
Here's the procedure:
- Create your kernel configuration (`.config` file) as usual. This
has to be done first so that ZFS's configure script is able to
detect kernel features correctly.
- Run `make prepare scripts` inside the kernel source tree.
- Run `./configure --enable-linux-builtin --with-linux=/usr/src/linux-...`
inside the ZFS directory.
- Run `./copy-builtin /usr/src/linux-...` inside the ZFS directory.
- In the kernel source tree, enable the `CONFIG_ZFS` option (e.g. using
`make menuconfig`). Note that this option depends on `CONFIG_SPL`
(see zfsonlinux/spl@744038069d).
- Build the kernel as usual.
ZFS module parameters can be set at boot time using the following syntax
on the kernel command line: `zfs.parameter_name=parameter_value`.
Note that you also need to rebuild the userspace tools (see
zfsonlinux/zfs@f09398cec6).

Issue #851
Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
$ ./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-...
