# Author: Linus Torvalds <torvalds@linux-foundation.org>

# 
#     Merge tag 'trace-v5.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing fixes from Steven Rostedt:
#     
#      - Check kprobe is enabled before unregistering from ftrace as it isn't
#        registered when disabled.
#     
#      - Remove kprobes enabled via command-line that is on init text when
#        freed.
#     
#      - Add missing RCU synchronization for ftrace trampoline symbols removed
#        from kallsyms.
#     
#      - Free trampoline on error path if ftrace_startup() fails.
#     
#      - Give more space for the longer PID numbers in trace output.
#     
#      - Fix a possible double free in the histogram code.
#     
#      - A couple of fixes that were discovered by sparse.
