Support custom build directories and move includes One of the neat tricks an autoconf style project is capable of is allow configurion/building in a directory other than the source directory. The major advantage to this is that you can build the project various different ways while making changes in a single source tree. For example, this project is designed to work on various different Linux distributions each of which work slightly differently. This means that changes need to verified on each of those supported distributions perferably before the change is committed to the public git repo. Using nfs and custom build directories makes this much easier. I now have a single source tree in nfs mounted on several different systems each running a supported distribution. When I make a change to the source base I suspect may break things I can concurrently build from the same source on all the systems each in their own subdirectory. wget -c http://github.com/downloads/behlendorf/zfs/zfs-x.y.z.tar.gz tar -xzf zfs-x.y.z.tar.gz cd zfs-x-y-z ------------------------- run concurrently ---------------------- <ubuntu system> <fedora system> <debian system> <rhel6 system> mkdir ubuntu mkdir fedora mkdir debian mkdir rhel6 cd ubuntu cd fedora cd debian cd rhel6 ../configure ../configure ../configure ../configure make make make make make check make check make check make check This change also moves many of the include headers from individual incude/sys directories under the modules directory in to a single top level include directory. This has the advantage of making the build rules cleaner and logically it makes a bit more sense.

Unconditionally load core kernel modules Loading and unloading the zlib modules as part of the zfs.sh script has proven a little problematic for a few reasons. * First, your kernel may not need to load either zlib_inflate or zlib_deflate. This functionality may be built directly in to your kernel. It depends entirely on what your distribution decided was the right thing to do. * Second, even if you do manage to load the correct modules you may not be able to unload them. There may other consumers of the modules with a reference preventing the unload. To avoid both of these issues the test scripts have been updated to attempt to unconditionally load all modules listed in KERNEL_MODULES. If the module is successfully loaded you must have needed it. If the module can't be loaded that almost certainly means either it is built in to your kernel or is already being used by another consumer. In both cases this is not an issue and we can move on to the spl/zfs modules. Finally, by removing these kernel modules from the MODULES list we ensure they are never unloaded during 'zfs.sh -u'. This avoids the issue of the script failing because there is another consumer using the module we were not aware of. In other words the script restricts unloading modules to only the spl/zfs modules. Closes #78
