  "message": "[PATCH] aio: optimize io_submit_one()\n\nThis patch optimizes io_submit_one to call aio_run_iocb() directly if\nctx-\u003erun_list is empty.  When the list is empty, the operation of adding to\nthe list, then call to __aio_run_iocbs() is unnecessary because these\noperations are done in one atomic step.  ctx-\u003erun_list always has only one\nelement in this case.  This optimization speeds up industry standard db\ntransaction processing benchmark by 0.2%.\n\nSigned-off-by: Ken Chen \u003ckenneth.w.chen@intel.com\u003e\nCc: Benjamin LaHaise \u003cbcrl@kvack.org\u003e\nCc: Suparna Bhattacharya \u003csuparna@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
