Don Brady dae3e9ea21 OpenZFS 9465 - ARC check for 'anon_size > arc_c/2' can stall the system
In the case of one pool being built on another pool, we want
to make sure we don't end up throttling the lower (backing)
pool when the upper pool is the majority contributor to dirty
data. To insure we make forward progress during throttling, we
also check the current pool's net dirty data and only throttle
if it exceeds zfs_arc_pool_dirty_percent of the anonymous dirty
data in the cache.

Porting Notes:
* The new global variables zfs_arc_dirty_limit_percent,
  zfs_arc_anon_limit_percent, and zfs_arc_pool_dirty_percent
  were intentially not added as tunable module parameters.
