Brian Behlendorf e76f4bf11d Add dnlc_reduce_cache() support 
Provide the dnlc_reduce_cache() function which attempts to prune
cached entries from the dcache and icache.  After the entries are
pruned any slabs which they may have been using are reaped.

Note the API takes a reclaim percentage but we don't have easy
access to the total number of cache entries to calculate the
reclaim count.  However, in practice this doesn't need to be
exactly correct.  We simply need to reclaim some useful fraction
(but not all) of the cache.  The caller can determine if more
needs to be done.

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
