#     Merge tag 'trace-v6.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
#     
#     Pull tracing fixes from Steven Rostedt:
#     
#      - 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 commit
#        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
#     
#     * tag 'trace-v6.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
#       tracing/hwlat: Replace sched_setaffinity with set_cpus_allowed_ptr
#       ring-buffer: remove obsolete comment for free_buffer_page()
#       tracing: Make splice_read available again
#       ftrace: Set direct_ops storage-class-specifier to static
#       trace/hwlat: Do not start per-cpu thread if it is already running
#       trace/hwlat: Do not wipe the contents of per-cpu thread data
#       tracing/osnoise: set several trace_osnoise.c variables storage-class-specifier to static
#       tracing: Fix wrong return in kprobe_event_gen_test.c
