Alexander Motin d0687a01d7 MFV r284763: 5981 Deadlock in dmu_objset_find_dp ... illumos/illumos-gate@1d3f896f54 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.
