aka Illumos 6513

Short summary: Pools with hole_birth feature enabled are susceptible to
irreversible damage interfering with, in particular, proper zfs send/receive
behavior. The bug fix is in, but does not repair damage already
inflicted to the pool.

>From the ZoL bugreport, user pcd1193182:

 > The fix for illumos 6513 will solve this problem, but not retroactively.
 > In other words, any pools that already have this state will not be fixed;
 > on such pools, the hole BPs already have their birth times set to zero,
 > and zfs has no way of telling which ones are bugged and which are right.
 > Any new pools, created after the fix has been applied, will work.
