Add QUEUE_MACRO_DEBUG_TRACE and QUEUE_MACRO_DEBUG_TRASH as proper kernel options. While here, alpha-sort the debug section of sys/conf/options. Enable QUEUE_MACRO_DEBUG_TRASH in amd64 GENERIC (but not GENERIC-NODEBUG) kernels. It is similar in nature and cost to other use-after-free pointer trashing we do in GENERIC. It is probably reasonable to enable in any arch GENERIC kernel that defines INVARIANTS.

# GENERIC-NODEBUG -- WITNESS and INVARIANTS free kernel configuration file
|
|
# for FreeBSD/amd64
|
|
#
|
|
# This configuration file removes several debugging options, including
|
|
# WITNESS and INVARIANTS checking, which are known to have significant
|
|
# performance impact on running systems. When benchmarking new features
|
|
# this kernel should be used instead of the standard GENERIC.
|
|
# This kernel configuration should never appear outside of the HEAD
|
|
# of the FreeBSD tree.
|
|
#
|
|
# For more information on this file, please read the config(5) manual page,
|
|
# and/or the handbook section on Kernel Configuration Files:
