Brian Behlendorf fadd0c4da1 Evict meta data from ghost lists + l2arc headers 
When the meta limit is exceeded the ARC evicts some meta data
buffers from the mfu+mru lists.  Unfortunately, for meta data
heavy workloads it's possible for these buffers to accumulate
on the ghost lists if arc_c doesn't exceed arc_size.

To handle this case arc_adjust_meta() has been entended to
explicitly evict meta data buffers from the ghost lists in
proportion to what was evicted from the mfu+mru lists.

If this is insufficient we request that the VFS release
some inodes and dentries.  This will result in the release
of some dnodes which are counted as 'other' metadata.
