Bug ID: 48353
           Summary: Use In-Reply-To when identifying patch series
           Product: Wine-Testbot
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The TestBot detects patchsets from the n/N pattern in the subject and then
matches the different parts together based on the From email address and the
total number of parts. This means if the TestBot receives the parts of two
patchsets with the same number of parts and from the same developer at the same
time it is likely to mix elements of the two patchsets, and thus fail to test
them.

However it is customary for patches in a series to all reference the first
email in the patch series through the In-Reply-To and Message-ID fields. This
could be used to resolve ambiguities in such a case.

However we may not want to use this as the sole way to attach parts to the
patchset in case setting In-Reply-To is not possible for some reason.
