Linus Torvalds eaba52d63b Tracing fixes for 6.3:

- Fix setting affinity of hwlat threads in containers
   Using sched_set_affinity() has unwanted side effects when being
   called within a container. Use set_cpus_allowed_ptr() instead.
 
 - Fix per cpu thread management of the hwlat tracer
   * Do not start per_cpu threads if one is already running for the CPU.
   * When starting per_cpu threads, do not clear the kthread variable
     as it may already be set to running per cpu threads
 
 - Fix return value for test_gen_kprobe_cmd()
   On error the return value was overwritten by being set to
   the result of the call from kprobe_event_delete(), which would
   likely succeed, and thus have the function return success.
 
 - Fix splice() reads from the trace file that was broken by
   36e2c7421f02 ("fs: don't allow splice read/write without explicit ops")
 
 - Remove obsolete and confusing comment in ring_buffer.c
   The original design of the ring buffer used struct page flags
   for tricks to optimize, which was shortly removed due to them
   being tricks. But a comment for those tricks remained.
 
 - Set local functions and variables to static
