  "message": "Btrfs: optimize leaf_space_used\n\nThis gets called at least 4 times for every level while adding an object,\nand it involves 3 kmapping calls, which on my box take about 5us a piece.\nSo instead use a token, which brings us down to 1 kmap call and makes this\nfunction take 1/3 of the time per call.
