Since a node may be marked inactive well before it is reaped from the list, add a new flag solely to track list membership, and employ it in some basic list integrity assertions to catch bad actors.

Catch up to that fact and revert to their recommended match of BSD-2-Clause.

Unhide more material from sys/mount.h and sys/ufs/ufs/inode.h, sys/ufs/ufs/ufsmount.h for consumption of userspace tools, with the same caveat. Remove unacceptable hack from usr.sbin/makefs which relied on sys/buf.h being unusable in userspace, where it override struct buf with its own definition. Instead, provide struct m_buf and struct m_vnode and adapt code to use local variants.

In particular this eliminates contention on said lock while using bhyve with multiple vms.

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. 2015-01-19T17:36:52Z Konstantin Belousov kib@FreeBSD.org 2015-01-19T17:36:52Z urn:sha1:3b50dff506e494f7aab6dee427f331a6c9133a37 in r277199.
