  "message": "workqueue: introduce WORK_OFFQ_FLAG_*\n\nLow WORK_STRUCT_FLAG_BITS bits of work_struct-\u003edata contain\nWORK_STRUCT_FLAG_* and flush color.  If the work item is queued, the\nrest point to the cpu_workqueue with WORK_STRUCT_CWQ set; otherwise,\nWORK_STRUCT_CWQ is clear and the bits contain the last CPU number -\neither a real CPU number or one of WORK_CPU_*.\n\nScheduled addition of mod_delayed_work[_on]() requires an additional\nflag, which is used only while a work item is off queue.  There are\nmore than enough bits to represent off-queue CPU number on both 32 and\n64bits.  This patch introduces WORK_OFFQ_FLAG_* which occupy the lower\npart of the @work-\u003edata high bits while off queue.  This patch doesn\u0027t\ndefine any actual OFFQ flag yet.\n\nOff-queue CPU number is now shifted by WORK_OFFQ_CPU_SHIFT, which adds\nthe number of bits used by OFFQ flags to WORK_STRUCT_FLAG_SHIFT, to\nmake room for OFFQ flags.\n\nTo avoid shift width warning with large WORK_OFFQ_FLAG_BITS, ulong\ncast is added to WORK_STRUCT_NO_CPU and, just in case, BUILD_BUG_ON()\nto check that there are enough bits to accomodate off-queue CPU number\nis added.\n\nThis patch doesn\u0027t make any functional difference.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n",
