I had an error saying that `regcache_sync` had 2 fields named `type` while using libtraceevent. This was the format of this event: $ sudo cat /sys/kernel/debug/tracing/events/regmap/regcache_sync/format name: regcache_sync ID: 1216 format: field:unsigned short common_type; offset:0; size:2; signed:0; field:unsigned char common_flags; offset:2; size:1; signed:0; field:unsigned char common_preempt_count; offset:3; size:1; signed:0; field:int common_pid; offset:4; size:4; signed:1; field:__data_loc char[] name; offset:8; size:4; signed:1; field:__data_loc char[] status; offset:12; size:4; signed:1; field:__data_loc char[] type; offset:16; size:4; signed:1; field:int type; offset:20; size:4; signed:1; print fmt: "%s type=%s status=%s", __get_str(name), __get_str(type), __get_str(status) Erase the `int field` type, who was not assigned. This field was introduce by mistake and this commit removes it. This is the format of this event after the fix: $ sudo cat /sys/kernel/debug/tracing/events/regmap/regcache_sync/format name: regcache_sync ID: 1266 format: field:unsigned short common_type; offset:0; size:2; signed:0; field:unsigned char common_flags; offset:2; size:1; signed:0; field:unsigned char common_preempt_count; offset:3; size:1; signed:0; field:int common_pid; offset:4; size:4; signed:1; field:__data_loc char[] name; offset:8; size:4; signed:1; field:__data_loc char[] status; offset:12; size:4; signed:1; field:__data_loc char[] type; offset:16; size:4; signed:1; print fmt: "%s type=%s status=%s", __get_str(name), __get_str(type), __get_str(status) Signed-off-by: Philippe Duplessis-Guindon <pduplessis@xxxxxxxxxxxx> --- drivers/base/regmap/trace.h | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/base/regmap/trace.h b/drivers/base/regmap/trace.h index d4066fa079ab..9abee14df9ee 100644 --- a/drivers/base/regmap/trace.h +++ b/drivers/base/regmap/trace.h @@ -126,7 +126,6 @@ TRACE_EVENT(regcache_sync, __string( name, regmap_name(map) ) __string( status, status ) __string( type, type ) - __field( int, type ) ), TP_fast_assign( -- 2.25.1
