Reference count every entry and exit from the condition variable functions: cv_wait(), cv_wait_timeout(), cv_signal(), cv_broadcast(). This allows us to safely block in cv_destroy() until all consumers have been scheduled and are no longer accessing the condition variable memory. In addition poison the magic value at the start of cv_destroy() to ensure there are never any new callers after cv_destroy() is called. The consumer is responsible for ensuring this never occurs.

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