Previous version is here. https://lore.kernel.org/bpf/162598881438.1222130.11530594038964049135.stgit@devnote2/ This version is rebased on the latest tip/master and Punit's cleanup series; https://lore.kernel.org/linux-csky/20210727133426.2919710-1-punitagrawal@gmail.com/ Just fixed some conflicts, basically no change. I pushed his series and this series as the 'kprobes/cleanup' branch on my tree. So you can pull the series (and Punit's series too) from the branch below. git://git.kernel.org/pub/scm/linux/kernel/git/mhiramat/linux.git kprobes/cleanup Thank you, --- Masami Hiramatsu (6): kprobes: treewide: Cleanup the error messages for kprobes kprobes: Fix coding style issues kprobes: Use IS_ENABLED() instead of kprobes_built_in() kprobes: Add assertions for required lock kprobes: treewide: Use 'kprobe_opcode_t *' for the code address in get_optimized_kprobe() kprobes: Use bool type for functions which returns boolean value arch/arm/probes/kprobes/core.c | 4 arch/arm/probes/kprobes/opt-arm.c | 7 - arch/arm64/kernel/probes/kprobes.c | 5 - arch/csky/kernel/probes/kprobes.c | 10 + arch/mips/kernel/kprobes.c | 11 + arch/powerpc/kernel/optprobes.c | 6 - arch/riscv/kernel/probes/kprobes.c | 11 + arch/s390/kernel/kprobes.c | 4 arch/x86/kernel/kprobes/opt.c | 6 - include/linux/kprobes.h | 64 +++---- kernel/kprobes.c | 313 +++++++++++++++++++----------------- kernel/trace/trace_kprobe.c | 2 12 files changed, 226 insertions(+), 217 deletions(-) -- Masami Hiramatsu (Linaro)
