Tim Chase 6f7acfc9c9 Prevent arc_c collapse 
Adjusting arc_c directly is racy because it can happen in the context
of multiple threads.  It should always be >= 2 * maxblocksize.  Set it
to a known valid value rather than adjusting it directly.

In addition refactor arc_shrink() to a simpler structure, protect against
underflow in the calculation of the new arc_c value.

Native ZFS for Linux!

ZFS is an advanced file system and volume manager which was originally developed for Solaris and is now maintained by the Illumos community.

ZFS on Linux, which is also known as ZoL, is currently feature complete. It includes fully functional and stable SPA, DMU, ZVOL, and ZPL layers.

Full documentation for installing ZoL on your favorite Linux distribution can be found at: http://zfsonlinux.org
