  "message": "blktrace: Remove blk_fill_rwbs_rq.\n\nIf we enable trace events to trace block actions, We use\nblk_fill_rwbs_rq to analyze the corresponding actions\nin request\u0027s cmd_flags, but we only choose the minor 2 bits\nfrom it, so most of other flags(e.g, REQ_SYNC) are missing.\nFor example, with a sync write we get:\nwrite_test-2409  [001]   160.013869: block_rq_insert: 3,64 W 0 () 258135 + \u003d\n8 [write_test]\n\nSince now we have integrated the flags of both bio and request,\nit is safe to pass rq-\u003ecmd_flags directly to blk_fill_rwbs and\nblk_fill_rwbs_rq isn\u0027t needed any more.\n\nWith this patch, after a sync write we get:\nwrite_test-2417  [000]   226.603878: block_rq_insert: 3,64 WS 0 () 258135 +\u003d\n 8 [write_test]\n\nSigned-off-by: Tao Ma \u003cboyu.mt@taobao.com\u003e\nAcked-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n",
