Well, it's hardly can be compared with 
echo "block=ADDRESS_FROM_STACK" > /.../kmemleak

Frankly, I still found it useful (as you don't have to write in perl, awk, sed, python etc 
to see 50 lines (you are interested in) out of 1000.
You just watching reports.)

(well, maybe not as useful as with syslog.)
 
Anyway, the decision is yours. And let it be so.
Thanks.
