+# CONFIG_HIST_TRIGGERS_DEBUG:
+# 
+# Add "hist_debug" file for each event, which when read will
+# dump out a bunch of internal details about the hist triggers
+# defined on that event.
+# 
+# The hist_debug file serves a couple of purposes:
+# 
+#   - Helps developers verify that nothing is broken.
+# 
+#   - Provides educational information to support the details
+#     of the hist trigger internals as described by
+#     Documentation/trace/histogram-design.rst.
+# 
+# The hist_debug output only covers the data structures
+# related to the histogram definitions themselves and doesn't
+# display the internals of map buckets or variable values of
+# running histograms.
+# 
+# If unsure, say N.
+# 
+# Symbol: HIST_TRIGGERS_DEBUG [=n]
+# Type  : bool
+# Defined at kernel/trace/Kconfig:850
+#   Prompt: Hist trigger debug support
+#   Depends on: TRACING_SUPPORT [=y] && FTRACE [=y] && HIST_TRIGGERS [=y]
+#   Location:
+#     -> Kernel hacking
+#       -> Tracers (FTRACE [=y])
