Hi all,
I have a quick question.
I'm trying to resurrect a patch from the Linux-tiny patch suite,
to do accounting of kmalloc memory allocations. In testing it
with Linux 2.6.22, I've found a large number of kfrees of
NULL pointers.
Is this considered OK? Or should I examine the offenders
to see if something is coded badly?
It's perfectly correct to do it - though, if it's done very frequently
in certain cases, it might be more efficient to check for null before
the kfree, to avoid the function call overhead into kfree..
