  "message": "arena: fix xalloc minaddr|maxaddr\n\nTwo problems:\n- if you had a single segment that contained minaddr, we\u0027d skip that\nsegment and start with the *next* one.  Not only did this mean we\nskipped a perfectly good segment that could have had the fix, but we\nmight not have a *next* segment, causing an OOM / failure.\n\nThe fix was to find the BT that contained minaddr, not just the strict\nupper bound.  This means we need to handle the case where BT contains\nminaddr: hence try_start and try_size.\n\n- We\u0027d scan the list of all nodes starting from the upper bound (and now\nequality), regardless of whether or not they are free.  Yikes!\n\nSigned-off-by: Barret Rhoden \u003cbrho@cs.berkeley.edu\u003e\n",
