Hi,I am doing an ftrace plugin for Babeltrace 2 [1], and while I was parsing the event fields I had an error saying that `regcache_sync` has 2 fields named `type`. The problem seems to come from the drivers/base/regmap/trace.h file [2]. This is the patch where this was added: [3]. The `int field` type is not assigned, so I was wondering if it is normal that the field is there.
This is 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)
