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)
