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)"
* tag 'probes-fixes-v6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
rethook, fprobe: do not trace rethook related functions
fprobe: add recursion detection in fprobe_exit_handler
fprobe: make fprobe_kprobe_handler recursion free
rethook: use preempt_{disable, enable}_notrace in rethook_trampoline_handler
tracing: fprobe: Initialize ret valiable to fix smatch error
