  "message": "slab: use a singly-linked list for bufctls\n\nIt saves a pointer for each bufctl.\n\nI glanced at arena.c for the same thing.  The code for those\nFOREACH-remove_if_X are a little more involved, but not a big deal.  But\nthe big one is untrack_free_seg, which isn\u0027t called from a list-foreach.\n\nSigned-off-by: Barret Rhoden \u003cbrho@cs.berkeley.edu\u003e\n",
