Unfortunately it cannot\nALWAYS work without human aid. What's worse, when it cannot figure out\nthe base-commit, the whole \"git format-patch\" command will abort like\nthis\n\n        $ git format-patch -1\n        fatal: base commit shouldn't be in revision list\n\nThat fatal error makes it not a viable option to always turn on\n\"--base=auto\" in .gitconfig.\n\nWithout a fully-automated solution, I don't think many people will\nbother or remember to manually specify base-commit before sending\npatches out.\n\nTo effectively save the robot from \"base commit\" guessing works, what\nwe can do is to\n\n1) append \"parent-commit\"/\"parent-patch-id\" lines when git cannot\n   figure out and append the \"base-commit\"/\"prerequisite-patch-id\"\n   lines. So that the test robot always get the information to do\n   its job.\n\n2) advise kernel developers to run this once\n\n        git config format.useAutoBase yes\n\n   to configure \"--base=auto\" as the default behavior.\n\nThanks,\nFengguang\n"}]}
