Tim Chase 09fb30e5e9 Linux 4.6 compat: Fall back to d_prune_aliases() if necessary 
As of 4.6, the icache and dcache LRUs are memcg aware insofar as the
kernel's per-superblock shrinker is concerned.  The effect is that dcache
or icache entries added by a task in a non-root memcg won't be scanned
by the shrinker in the context of the root (or NULL) memcg.  This defeats
the attempts by zfs_sb_prune() to unpin buffers and can allow metadata to
grow uncontrollably.  This patch reverts to the d_prune_aliaes() method
in case the kernel's per-superblock shrinker is not able to free anything.
