I think, it is no big thing. The trick is probably to say nothing at all
about the cause, when it is not clear. It's a mind thing. As soon as the
association is brought up, everybody thinks along those lines.  :)

If you leave out the "ext4/readahead related", then people will still
know that it might be ext4 readahead related because you posted the
backtrace, but they will not have their mind turned to that. Instead
they will think: oh a backtrace... there were some people shouting
about backtraces in my area, let's see if it is realted. 

But of course, sometimes putting blame somewhere also does help getting
attention. After all "CORRUPTION IN FILESYSTEM XYZ" sticks out more
than "partial trace of a thing i don't know anything at all".

Cheers,
Flo
