Add a test designed to generate contention on the taskq spinlock by using a large number of threads (100) to perform a large number (131072) of trivial work items from a single queue. This simulates conditions that may occur with the zio free taskq when a 1TB file is removed from a ZFS filesystem, for example. This test should always pass. Its purpose is to provide a benchmark to easily measure the effectiveness of taskq optimizations using statistics from the kernel lock profiler.

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
