Brian Behlendorf 6ef94aa67a Fix tsd_get/set() race with tsd_exit/destroy() 
The tsd_exit() and tsd_destroy() functions remove entries from
hash bins without taking the hash bin lock.  They do take the
table lock, but tsd_get() and tsd_set() only take the hash bin
lock to allow for maximum concurency.

The result is that while tsd_get() and tsd_set() are traversing
the hash bin list it can be modified by another thread in which
happens to hash to the same value.  To avoid this add the needed
locking to tsd_exit() and tsd_destroy().

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
