    I dunno, this looks like putting lipstick on a pig.

    What is the point in zeroing memory just before freeing it? afacit
    this is always done as a poor-man's poisoning operation.

    But the slab allocators _already_ do poisoning, and they do it better.
    And they do it configurably, whereas those sites you've been looking at
    are permanently slowing the kernel down.

    So I would cheerily merge and push patches titled "remove pointless
    memset before kfree".
