Merge tag 'trace-v5.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt:
- Use correct timestamp variable for ring buffer write stamp update
- Fix up before stamp and write stamp when crossing ring buffer sub
buffers
- Keep a zero delta in ring buffer in slow path if cmpxchg fails
- Fix trace_printk static buffer for archs that care
- Fix ftrace record accounting for ftrace ops with trampolines
- Fix DYNAMIC_FTRACE_WITH_DIRECT_CALLS dependency
- Remove WARN_ON in hwlat tracer that triggers on something that is OK
- Make "my_tramp" trampoline in ftrace direct sample code global
- Fixes in the bootconfig tool for better alignment management
