# Merge: 1f594fe7c907 571a2a50a8fc
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'probes-fixes-v6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
#     
#     Pull probes fixes from Masami Hiramatsu:
#     
#      - Initialize 'ret' local variables on fprobe_handler() to fix the
#        smatch warning. With this, fprobe function exit handler is not
#        working randomly.
#     
#      - Fix to use preempt_enable/disable_notrace for rethook handler to
#        prevent recursive call of fprobe exit handler (which is based on
#        rethook)
#     
#      - Fix recursive call issue on fprobe_kprobe_handler()
#     
#      - Fix to detect recursive call on fprobe_exit_handler()
#     
#      - Fix to make all arch-dependent rethook code notrace (the
#        arch-independent code is already notrace)"

#       rethook, fprobe: do not trace rethook related functions
