Can I make any use of kmemcheck if I don't have sysfs
kernel support enabled?

Kmemleak can scan output the memory and report the number of leaked
objects but if you need to get additional information about the leaked
objects (like backtrace), you need debugfs enabled.

How is this reporting done?  It will appear in dmesg output?

DEBUG_FS doesn't seem to be dependent on SYSFS but I never tried to
enable one without the other (you might be able to mount the DEBUG_FS
somewhere other than /sys/kernel/debug/).

I see. I was using 2.6.32 where it seems that debugfs depended on sysfs.
Decoupling was done some time later [1].

thanks,
Daniel.
