Log Message:
Add a new command, show all locks, which shows information of active locks
The command shows information of all active (i.e., being held) locks that are
tracked through either of LWPs or CPUs by the LOCKDEBUG facility. The /t
modifier additionally shows a backtrace for each LWP additionally. This
feature is useful for debugging especially to analyze deadlocks.
The command is useful only if LOCKDEBUG is enabled.
