Author: jilles Date: Sun Apr 25 12:50:30 2010 New Revision: 207187 URL: http://svn.freebsd.org/changeset/base/207187 Log: kvm(3): Mention that some of the functions use sysctl(3) instead of kmem. Additionally, because of sysctl(3) use (which is generally good), behaviour for crash dumps differs slightly from behaviour for live kernels and this will probably never be fixed entirely, so weaken that claim.
