9080 recursive enter of vdev_indirect_rwlock from vdev_indirect_remap() illumos/illumos-gate@bdfded42e6 A scenario came up where a callback executed by vdev_indirect_remap() on a vdev, calls vdev_indirect_remap() on the same vdev and tries to reacquire vdev_indirect_rwlock that was already acquired from the first call to vdev_indirect_remap(). The specific scenario, is that we want to remap a block pointer that is snapshoted but its dataset's remap_deadlist is not cached. So in order to add it we issue a read through a vdev_indirect_remap() on the same vdev, which brings up the aforementioned issue.
