 It seems that I have been misunderstanding the problem.
 "ZFS: gang block detected" won't even appear if boot code is too old.
 
 Having briefly glanced over the code and comparing it to the code in osol and in
 zio_gang_tree_issue(), I think the following change is needed.
 But I am not sure if it is a real fix for the issue at hand.
 
 If anyone can reproduce the problem, could you please test this change?
 Thanks!
