Author: bz Date: Mon Aug 10 10:58:43 2020 New Revision: 364075 URL: https://svnweb.freebsd.org/changeset/base/364075 Log: MC: add a note with reference to the discussion and history as-to why we are where we are now. The main thing is to try to get rid of the delayed freeing to avoid blocking on the taskq when shutting down vnets. X-Timeout: if you still see this before 14-RELEASE remove it.
