New Revision: 258858
URL: http://svnweb.freebsd.org/changeset/base/258858
Log:
Right now LOCK_DEBUG is enabled if KTR is on.
This is to support LOCK_LOG_* functionality effectively in debugging
environments but it is overkill because really LOCK_DEBUG should be on
only if (KTR_COMPILE & KTR_LOCK) is true.
Fix this by applying the correct logic.
In this process, move the KTR classes to its own header to reduce
namespace pollution.
