#     Merge tag 'trace-v5.2-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing fixes from Steven Rostedt:
#      "This includes three fixes:
#     
#        - Fix a deadlock from a previous fix to keep module loading and
#          function tracing text modifications from stepping on each other
#          (this has a few patches to help document the issue in comments)
#     
#        - Fix a crash when the snapshot buffer gets out of sync with the main
#          ring buffer
#     
#        - Fix a memory leak when reading the memory logs"
#     
#     * tag 'trace-v5.2-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
#       ftrace/x86: Anotate text_mutex split between ftrace_arch_code_modify_post_process() and ftrace_arch_code_modify_prepare()
#       tracing/snapshot: Resize spare buffer if size changed
#       tracing: Fix memory leak in tracing_err_log_open()
#       ftrace/x86: Add a comment to why we take text_mutex in ftrace_arch_code_modify_prepare()
#       ftrace/x86: Remove possible deadlock between register_kprobe() and ftrace_run_update_code()
