When compiling ZFS in user space gcc-4.6.0 correctly identifies the variable 'os' as being set but never used. This generates a warning and a build failure when using --enable-debug. However, the code is correct we only want to use 'os' for the kernel space builds. To suppress the warning the call was wrapped with a VERIFY() which has the nice side effect of ensuring the 'os' actually never is NULL. This was observed under Fedora 15. module/zfs/dsl_pool.c: In function ‘dsl_pool_create’: module/zfs/dsl_pool.c:229:12: error: variable ‘os’ set but not used [-Werror=unused-but-set-variable]
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
