Subject: [for-linus][PATCH 0/5] tracing: Fixes for 5.11-rc5


Tracing fixes:

 - Initialize tracing-graph-pause at task creation, not start of
   function tracing. Causes the pause counter to be corrupted.
 - Set "pause-on-trace" for latency tracers as that option breaks
   their output (regression).
 - Fix the wrong error return for setting kretprobes on future
   modules (before they are loaded).
 - Fix re-registering the same kretprobe.
 - Add missing value check for added RCU variable reload.

      tracing/kprobe: Fix to support kretprobe events on unloaded modules

      fgraph: Initialize tracing_graph_pause at task creation

Viktor Rosendahl (1):
      tracing: Use pause-on-trace with the latency tracers

Wang ShaoBo (1):
      kretprobe: Avoid re-registration of the same kretprobe earlier
