Author: kaktus Date: Sun Feb 16 17:11:54 2020 New Revision: 358004 URL: https://svnweb.freebsd.org/changeset/base/358004
Log: Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (5 of many) r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags.
