r1081136 was some sort of --record-only merge that just modified
mergeinfo. The trunk mergeinfo change matches the log message:

Modified: svn:mergeinfo
   Merged /subversion/branches/performance:r992904,1029230,1067697-1078365

but there are subtree mergeinfo changes that are harder to understand.
For subversion/libsvn_subr/svn_temp_serializer.c the change is:

Added: svn:mergeinfo
   Merged /subversion/trunk/subversion/libsvn_subr/svn_temp_serializer.c:r1067687-1072301

which refers to trunk not branches/performance, I don't think that is
correct. svn_temp_serializer.c didn't exist on trunk before 1072303, it
was created on the performance branch and merged/copied to trunk in
1072303, so that may be what caused the error.

For subversion/libsvn_subr/adler32.c the change is:

Modified: svn:mergeinfo
   Merged /subversion/branches/performance/subversion/libsvn_subr/adler32.c:r1067697-1078365

which does refer to the branch but doesn't have the two early revisions
992904 and 1029230. adler32.c didn't exist in libsvn_subr before
r1054277 when it was copied from libsvn_diff.

Stefan, can you recall how you did this merge?
