https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220691 --- Comment #7 from commit-hook@freebsd.org --- A commit references this bug: Author: avg Date: Tue Jul 18 07:41:39 UTC 2017 New revision: 321111 URL: https://svnweb.freebsd.org/changeset/base/321111 Log: fix a regression in r320452, ZFS ABD import I overlooked the fact that vdev_op_io_done hook is called even if the actual I/O is skipped, for example, in the case of a missing vdev. Arguably, this could be considered an issue in the zio pipeline engine, but for now I am adding defensive code to check for io_bp being NULL along with assertions that that happens only when it can be really expected.
