Ah, missed that.

But your other comment about checking the kmalloc is valid.  We should
not add new calls to kmalloc that doesn't check, let's not _add_ new
errors to the code :)

Bruce, care to split this up into individual patches, each doing only
one thing, and check for the return value of this call?
