Hi All, I’m facing compilation error in build after pulling in the stable kernel LTS(4.14.y) commit - https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-4.14.y&id=77322edb99f0176ec67a300b9f263719ba391b89
I tried this solution - https://github.com/lttng/lttng-modules/commit/7318a1e88c8097733f5a05529069e4e03c142cae But this also didn’t resolve my problem. | In file included from /home/snaaz/elm/8up/main/build_zcu/tmp/work/zcu102_zynqmp_mel-mel-linux/lttng-modules/2.10.9-r0/lttng-modules-2.10.9/probes/../probes/define_trace.h💯0, | from /home/snaaz/elm/8up/main/build_zcu/tmp/work/zcu102_zynqmp_mel-mel-linux/lttng-modules/2.10.9-r0/lttng-modules-2.10.9/probes/../instrumentation/events/lttng-module/writeback.h:735, | from /home/snaaz/elm/8up/main/build_zcu/tmp/work/zcu102_zynqmp_mel-mel-linux/lttng-modules/2.10.9-r0/lttng-modules-2.10.9/probes/lttng-probe-writeback.c:51: | /home/snaaz/elm/8up/main/build_zcu/tmp/work/zcu102_zynqmp_mel-mel-linux/lttng-modules/2.10.9-r0/lttng-modules-2.10.9/probes/../probes/lttng-tracepoint-event-impl.h:143:6: error: conflicting types for 'trace_writeback_queue_io' | void trace_##_name(_proto); | ^ | /home/snaaz/elm/8up/main/build_zcu/tmp/work/zcu102_zynqmp_mel-mel-linux/lttng-modules/2.10.9-r0/lttng-modules-2.10.9/probes/../probes/lttng-tracepoint-event-impl.h:55:2: note: in expansion of macro 'LTTNG_TRACEPOINT_EVENT_INSTANCE_MAP' | LTTNG_TRACEPOINT_EVENT_INSTANCE_MAP(map, name, map, PARAMS(proto), PARAMS(args)) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | /home/snaaz/elm/8up/main/build_zcu/tmp/work/zcu102_zynqmp_mel-mel-linux/lttng-modules/2.10.9-r0/lttng-modules-2.10.9/probes/../probes/lttng-tracepoint-event-impl.h:97:2: note: in expansion of macro 'LTTNG_TRACEPOINT_EVENT_MAP' | LTTNG_TRACEPOINT_EVENT_MAP(name, name, \ | ^~~~~~~~~~~~~~~~~~~~~~~~~~ | /home/snaaz/elm/8up/main/build_zcu/tmp/work/zcu102_zynqmp_mel-mel-linux/lttng-modules/2.10.9-r0/lttng-modules-2.10.9/probes/../instrumentation/events/lttng-module/writeback.h:375:1: note: in expansion of macro 'LTTNG_TRACEPOINT_EVENT' | LTTNG_TRACEPOINT_EVENT(writeback_queue_io, | ^~~~~~~~~~~~~~~~~~~~~~ | In file included from /home/snaaz/elm/8up/main/build_zcu/tmp/work-shared/zcu102-zynqmp-mel/kernel-source/include/trace/events/writeback.h:8:0, | from /home/snaaz/elm/8up/main/build_zcu/tmp/work/zcu102_zynqmp_mel-mel-linux/lttng-modules/2.10.9-r0/lttng-modules-2.10.9/probes/lttng-probe-writeback.c:33: | /home/snaaz/elm/8up/main/build_zcu/tmp/work-shared/zcu102-zynqmp-mel/kernel-source/include/linux/tracepoint.h:187:21: note: previous definition of 'trace_writeback_queue_io' was here | static inline void trace_##name(proto) \ | ^ | /home/snaaz/elm/8up/main/build_zcu/tmp/work-shared/zcu102-zynqmp-mel/kernel-source/include/linux/tracepoint.h:352:2: note: in expansion of macro '__DECLARE_TRACE' | __DECLARE_TRACE(name, PARAMS(proto), PARAMS(args), \ | ^~~~~~~~~~~~~~~ | /home/snaaz/elm/8up/main/build_zcu/tmp/work-shared/zcu102-zynqmp-mel/kernel-source/include/linux/tracepoint.h:488:2: note: in expansion of macro 'DECLARE_TRACE' | DECLARE_TRACE(name, PARAMS(proto), PARAMS(args)) | ^~~~~~~~~~~~~ | /home/snaaz/elm/8up/main/build_zcu/tmp/work-shared/zcu102-zynqmp-mel/kernel-source/include/trace/events/writeback.h:361:1: note: in expansion of macro 'TRACE_EVENT' | TRACE_EVENT(writeback_queue_io, Kindly look into it and do the needful.
