  "message": "[PATCH] Kill PF_SYNCWRITE flag\n\nA process flag to indicate whether we are doing sync io is incredibly\nugly. It also causes performance problems when one does a lot of async\nio and then proceeds to sync it. Part of the io will go out as async,\nand the other part as sync. This causes a disconnect between the\npreviously submitted io and the synced io. For io schedulers such as CFQ,\nthis will cause us lost merges and suboptimal behaviour in scheduling.\n\nRemove PF_SYNCWRITE completely from the fsync/msync paths, and let\nthe O_DIRECT path just directly indicate that the writes are sync\nby using WRITE_SYNC instead.\n\nSigned-off-by: Jens Axboe \u003caxboe@suse.de\u003e\n",
