There was some kind of process error here...

1) That commit somehow never made it to linux-next.

2) No Fixes tag.  Presumably Greg searches for Fixes tags before he back
ports patches.  The original commit 46c116b920eb ("ext4: verify dir
block before splitting it") has been back ported to stable already.

3) I don't know why I didn't send a patch for this bug.  I looked at it
on May 23 but never sent a patch.  Sorry?

4) There are a dozen other static checkers which are supposed to have
warned about this.  I search lore.kernel.org for 46c116b920eb
and 46c116b920ebec58031f0a78c5ea9599b0d2a371 but I couldn't find any
static checker warnings.
