Subject: Why is the kfree() argument const?
Date: Wed, 16 Jan 2008 17:32:23 +0100	[thread overview]
Message-ID: <87lk6pvii0.fsf@saeurebad.de> (raw)

Hi,

is there any reason why kfree() takes a const pointer just to degrade it
with the call to slab_free()/__cache_free() again?  The promise that the
pointee is not modified is just bogus in this case, anyway, isn't it?
