Linus Torvalds 4d66020dce Tracing updates for 5.17:
New:
 
 - The Real Time Linux Analysis (RTLA) tool is added to the tools directory.
 
 - Can safely filter on user space pointers with: field.ustring ~ "match-string"
 
 - eprobes can now be filtered like any other event.
 
 - trace_marker(_raw) now uses stream_open() to allow multiple threads to safely
   write to it. Note, this could possibly break existing user space, but we will
   not know until we hear about it, and then can revert the change if need be.
 
 - New field in events to display when bottom halfs are disabled.
 
 - Sorting of the ftrace functions are now done at compile time instead of
   at bootup.
 
 Infrastructure changes to support future efforts:
 
 - Added __rel_loc type for trace events. Similar to __data_loc but the offset
   to the dynamic data is based off of the location of the descriptor and not
   the beginning of the event. Needed for user defined events.
 
 - Some simplification of event trigger code.
 
 - Make synthetic events process its callback better to not hinder other
   event callbacks that are registered. Needed for user defined events.
 
 And other small fixes and clean ups.
