I am just saying that the information already present in the block trace
point can be used to get this "alignment" info, right? And userspace can do
the work of reading those trace events to find this "alignment" info.

So, maybe this is better to have integrated in blktrace tool?

Sure, or whatever tool which can process this information. I just don'tsee why the kernel should be burdened with this.


Thanks,
John
