RT added two bytes to trace migrate disable counting to the trace events and used two bytes of the padding to make the change. The structures and all were updated correctly, but the display in the event formats was not: cat /debug/tracing/events/sched/sched_switch/format name: sched_switch ID: 51 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:unsigned short common_migrate_disable; offset:8; size:2; signed:0; field:int common_padding; offset:10; size:2; signed:0; The field for common_padding has the correct size and offset, but the use of "int" might confuse some parsers (and people that are reading it). This needs to be changed to "unsigned short".
