MFC r286689: 5981 Deadlock in dmu_objset_find_dp
illumos/illumos-gate@1d3f896f5469c69c1339890ec3d68e9feddb0343
https://www.illumos.org/issues/5981
When dmu_objset_find_dp gets called with a read lock held, it fans out
the work to the task queue. Each task in turn acquires its own read
lock before calling the callback. If during this process anyone tries
to a acquire a write lock, it will stall all read lock requests.Thus
the tasks will never finish, the read lock of the caller will never
get freed and the write lock never acquired. deadlock.

MFC r286686: 5269 zpool import slow
illumos/illumos-gate@12380e1e701fda28c9e9f32d01cafb54af279eb5
https://www.illumos.org/issues/5269
When importing a pool (at boot or with zpool import) with many
filesystem, the process can take minutes. It doesn't matter whether
the pool has been exported cleanly or uncleanly. The problem is that
each dataset has its own log chain. On import, all datasets have to be
checked if there are logs to replay. The idea is to speed up this
process by paralellizing it.
