Newer versions of gcc are getting smart enough to detect the sloppy syntax used for the autoconf tests. It is now generating warnings for unused/undeclared variables. Newer version of gcc even have the -Wunused-but-set-variable option set by default. This isn't a problem except when -Werror is set and they get promoted to an error. In this case the autoconf test will return an incorrect result which will result in a build failure latter on. To handle this I'm tightening up many of the autoconf tests to explicitly mark variables as unused to suppress the gcc warning. Remember, all of the autoconf code can never actually be run we just want to get a clean build error to detect which APIs are available. Never using a variable is absolutely fine for this. |

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
Full documentation for building, configuring, and using the SPL can be found at: http://zfsonlinux.org
