Subject: kfree(0) - ok?
Date: Tue, 14 Aug 2007 15:59:23 -0700	[thread overview]
Message-ID: <46C233CB.9000602@am.sony.com> (raw)

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?

Thanks,
 -- Tim
