Honestly, I did not get the meaning until I looked at the sample
usage added by the 2nd patch.

The term "anonymous structures" has another meaning in C++. It is
used for structures without any name that are defined inside a named
structure.

Something like this might be better:

"crash: Add VMCOREINFO macro to define offset in a struct declared by typedef

 The existing macro VMCOREINFO_OFFSET() can't be used for structures
 declared via typedef because "struct" is not part of type definition.

 Create another macro for this purpose."


Anyway, thanks a lot for the prototype of crash implementation.
I am happy that it is possible.

Best Regards,
Petr

PS: It might take few more days until I send some feedback for the
other patches. They are a bit more complex ;-)
