I use pahole to read vmlinux.o directly with defconfig and
CONFIG_DEBUG_INFO enabled, the result shows 22 structs prefixed with
trace_event_raw_ that have at least one hole.

I was thinking of pahole too ;-)

But the information can also be captured from the format files with simple
scripts as well. And perhaps be more tuned to see if there's actually a fix
for them, and ignore reporting it if there is no fix, as all trace events
are 4 byte aligned, and if we are off by one, sometimes it doesn't matter.

I am going to send a patch to fix this issue later. There are many
events have more than 1 holes, I am trying to pick up the events that are
really to be fixed.
