Hi kbuild test robot folks,

I attempted to use the --base option with git format-patch as suggested
by Philip, but the bot still sent me mail (addressed only to myself and
cc'd kbuild-...@01.org) about build test ERRORs against the wrong base:

> [auto build test ERROR on v4.16]
> [also build test ERROR on next-20180424]
> [cannot apply to linus/master jikos-livepatching/for-next]

I'm assuming operator error :(  Here's a summary of my workflow:

* Save an .mbox of the entire base patchset, as posted to the
live-patching list:

  https://lkml.org/lkml/2018/3/23/665

* Create a "base" branch and apply the mbox:

  % git checkout -b test_base v4.16
  Switched to a new branch 'test_base'

  % git am /tmp/pm.mbox
  Applying: livepatch: Use lists to manage patches, objects and functions
  Applying: livepatch: Free only structures with initialized kobject
  Applying: livepatch: Add atomic replace
  Applying: livepatch: Add an extra flag to distinguish registered   patches
  Applying: livepatch: Remove replaced patches from the stack
  Applying: livepatch: Remove Nop structures when unused
  Applying: livepatch: Allow to replace even disabled patches
  Applying: livepatch: Atomic replace and cumulative patches documentation

* Create a new dev branch from the base, make a trivial change and commit:

  % git checkout -b test_branch test_base
  % sed -i 's/^EXTRAVERSION =/EXTRAVERSION = .test/' Makefile
  % git commit Makefile -m 'test commit'

* Create .patch files with --base:

  % git format-patch --base=v4.16 -1 --cover-letter
  % grep -e '^base-commit' -e 'prereq' 0000-cover-letter.patch
  base-commit: 0adb32858b0bddf4ada5f364a84ed60b196dbcda

I notice that these patch-ids are only added to the cover-letter... do I
need to force them each individual patch as well?  /confused

Thanks,

-- Joe
