  "message": "percpu: remove unit_size power-of-2 restriction\n\nImpact: allow unit_size to be arbitrary multiple of PAGE_SIZE\n\nIn dynamic percpu allocator, there is no reason the unit size should\nbe power of two.  Remove the restriction.\n\nAs non-power-of-two unit size means that empty chunks fall into the\nsame slot index as lightly occupied chunks which is bad for reclaming.\nReserve an extra slot for empty chunks.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n",
