In discussion on LKML (https://lkml.org/lkml/2014/11/28/158), Russell King suggests to move all probe related code to arch/arm/probes. This patch does the work. Due to dependency on 'arch/arm/kernel/patch.h', this patch also moves patch.h to 'arch/arm/include/asm/patch.h', and related '#include' directives are also midified to '#include <asm/patch.h>'. Following is an overview of this patch: ./arch/arm/kernel/ ./arch/arm/probes/ |-- Makefile |-- Makefile |-- probes-arm.c ==> |-- decode-arm.c |-- probes-arm.h ==> |-- decode-arm.h |-- probes-thumb.c ==> |-- decode-thumb.c |-- probes-thumb.h ==> |-- decode-thumb.h |-- probes.c ==> |-- decode.c |-- probes.h ==> |-- decode.h | |-- kprobes | | |-- Makefile |-- kprobes-arm.c ==> | |-- actions-arm.c |-- kprobes-common.c ==> | |-- actions-common.c |-- kprobes-thumb.c ==> | |-- actions-thumb.c |-- kprobes.c ==> | |-- core.c |-- kprobes.h ==> | |-- core.h |-- kprobes-test-arm.c ==> | |-- test-arm.c |-- kprobes-test.c ==> | |-- test-core.c |-- kprobes-test.h ==> | |-- test-core.h |-- kprobes-test-thumb.c ==> | `-- test-thumb.c | `-- uprobes | |-- Makefile |-- uprobes-arm.c ==> |-- actions-arm.c |-- uprobes.c ==> |-- core.c |-- uprobes.h ==> `-- core.h | `-- patch.h ==> arch/arm/include/asm/patch.h Signed-off-by: Wang Nan <wangnan0@huawei.com> v1 -> v2: - Rename source files to describe their functions. - Add Makefiles in kprobes and uprobes directories. --- arch/arm/Makefile | 1 + arch/arm/{kernel => include/asm}/patch.h | 0 arch/arm/kernel/Makefile | 16 ++-------------- arch/arm/kernel/jump_label.c | 2 +- arch/arm/kernel/patch.c | 3 +-- arch/arm/probes/Makefile | 7 +++++++ arch/arm/{kernel/probes-arm.c => probes/decode-arm.c} | 7 ++++--- arch/arm/{kernel/probes-arm.h => probes/decode-arm.h} | 4 +++- .../arm/{kernel/probes-thumb.c => probes/decode-thumb.c} | 6 +++--- .../arm/{kernel/probes-thumb.h => probes/decode-thumb.h} | 4 +++- arch/arm/{kernel/probes.c => probes/decode.c} | 4 ++-- arch/arm/{kernel/probes.h => probes/decode.h} | 2 +- arch/arm/probes/kprobes/Makefile | 11 +++++++++++ .../kprobes-arm.c => probes/kprobes/actions-arm.c} | 6 +++--- .../kprobes-common.c => probes/kprobes/actions-common.c} | 4 ++-- .../kprobes-thumb.c => probes/kprobes/actions-thumb.c} | 6 +++--- arch/arm/{kernel/kprobes.c => probes/kprobes/core.c} | 8 ++++---- arch/arm/{kernel/kprobes.h => probes/kprobes/core.h} | 3 ++- .../kprobes-test-arm.c => probes/kprobes/test-arm.c} | 2 +- .../kprobes-test.c => probes/kprobes/test-core.c} | 8 ++++---- .../kprobes-test.h => probes/kprobes/test-core.h} | 2 +- .../kprobes-test-thumb.c => probes/kprobes/test-thumb.c} | 4 ++-- arch/arm/probes/uprobes/Makefile | 2 ++ .../uprobes-arm.c => probes/uprobes/actions-arm.c} | 6 +++--- arch/arm/{kernel/uprobes.c => probes/uprobes/core.c} | 6 +++--- arch/arm/{kernel/uprobes.h => probes/uprobes/core.h} | 0 26 files changed, 69 insertions(+), 55 deletions(-) rename arch/arm/{kernel => include/asm}/patch.h (100%) create mode 100644 arch/arm/probes/Makefile rename arch/arm/{kernel/probes-arm.c => probes/decode-arm.c} (99%) rename arch/arm/{kernel/probes-arm.h => probes/decode-arm.h} (97%) rename arch/arm/{kernel/probes-thumb.c => probes/decode-thumb.c} (99%) rename arch/arm/{kernel/probes-thumb.h => probes/decode-thumb.h} (97%) rename arch/arm/{kernel/probes.c => probes/decode.c} (99%) rename arch/arm/{kernel/probes.h => probes/decode.h} (99%) create mode 100644 arch/arm/probes/kprobes/Makefile rename arch/arm/{kernel/kprobes-arm.c => probes/kprobes/actions-arm.c} (99%) rename arch/arm/{kernel/kprobes-common.c => probes/kprobes/actions-common.c} (98%) rename arch/arm/{kernel/kprobes-thumb.c => probes/kprobes/actions-thumb.c} (99%) rename arch/arm/{kernel/kprobes.c => probes/kprobes/core.c} (99%) rename arch/arm/{kernel/kprobes.h => probes/kprobes/core.h} (96%) rename arch/arm/{kernel/kprobes-test-arm.c => probes/kprobes/test-arm.c} (99%) rename arch/arm/{kernel/kprobes-test.c => probes/kprobes/test-core.c} (99%) rename arch/arm/{kernel/kprobes-test.h => probes/kprobes/test-core.h} (99%) rename arch/arm/{kernel/kprobes-test-thumb.c => probes/kprobes/test-thumb.c} (99%) create mode 100644 arch/arm/probes/uprobes/Makefile rename arch/arm/{kernel/uprobes-arm.c => probes/uprobes/actions-arm.c} (98%) rename arch/arm/{kernel/uprobes.c => probes/uprobes/core.c} (98%) rename arch/arm/{kernel/uprobes.h => probes/uprobes/core.h} (100%) diff --git a/arch/arm/kernel/uprobes.h b/arch/arm/probes/uprobes/core.h similarity index 100% rename from arch/arm/kernel/uprobes.h rename to arch/arm/probes/uprobes/core.h
