Hi all, This is the 2nd version of patch series to fix the ftrace rethook recursion problem. v1: https://lore.kernel.org/linux-trace-kernel/cover.1684120990.git.zegao@xxxxxxxxxxx/T/ +++#md4c0bae6a6cae28dadf2a2c6105ff140b35fddea As Steven suggested, this version removes unnecessary notrace annotations from fprobe and rethook functions from v1 [PATCH 2,3,4/4] and replaces with makefile changes to filter out compiler flags which ftrace depends upon for rethook related objects. Ze Gao (4): rethook: use preempt_{disable, enable}_notrace in rethook_trampoline_handler fprobe: make fprobe_kprobe_handler recursion free fprobe: add recursion detection in fprobe_exit_handler rehook, fprobe: do not trace rethook related functions arch/riscv/kernel/probes/Makefile | 2 + arch/s390/kernel/Makefile | 1 + arch/x86/kernel/Makefile | 1 + kernel/trace/fprobe.c | 72 ++++++++++++++++++++++++------- kernel/trace/rethook.c | 4 +- 5 files changed, 63 insertions(+), 17 deletions(-) -- 2.40.1
