Discussed on lkml, with you, and at Linux Plumbers. It's been in -next for the entire dev cycle. Before the merge window closes, I'd like to send the treewide change (generated from the Coccinelle script included here), which mechanically converts almost 20k callsites from kmalloc* to kmalloc_obj*: 8007 files changed, 19980 insertions(+), 20838 deletions(-) This change needed fixes for mismatched types (since now the return type from allocations is a pointer to the requested type, not "void *"), and I've been fixing these over the last 4 releases. These fixes have mostly been trivial mismatches with const qualifiers or accidentally identical sizes (e.g. same object size: "struct kvec" vs "struct iovec", or differing pointers to pointers), but I did catch one case of too-small allocation.
