Subject: Why is the kfree() argument const?
Date: Wednesday, January 16, 2008 - 12:32 pm

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?
