- * Logical Channel Structure.  One instance per channel.

- * Locking Hierarchy
- * Each lock has a postfix that describes the locking level.  If multiple locks
- * are required, only increasing lock hierarchy numbers may be locked which
- * ensures avoiding a deadlock.
- *
- * Locking Example
- * If state_lock_lhb1 is currently held and the TX list needs to be
- * manipulated, then tx_lock_lhb2 may be locked since it's locking hierarchy
- * is greater.  However, if tx_lock_lhb2 is held, then state_lock_lhb1 may
- * not be acquired since it would result in a deadlock.
- *
- * Note that the Line Discipline locks (*_lha) should always be acquired
- * before the logical channel locks.

+====================
+
+NAME
+----
+perf-script-json-export - Export trace data to JSON
+
+SYNOPSIS
+--------
+[verse]
+'perf script' -g JSON:<script>
+'perf script' -g <script.json>
+'perf script' -s JSON:<script> [option]*
+'perf script' -s <script.json> [option]*
+
+DESCRIPTION
+-----------
+
+This perf script option is used to export perf script data using JSON
+format.  JSON export extesion is identified either by the 'JSON:'
+prefix or the '.json' file extension.
+
+Both command forms export JSON fomatted data.  The '-g'/'--gen-script'
+option does not include actual event data.  Only Definitions.  '-s'
+version includes events and definition data (by default).
+
