[PATCH v3 01/54] vmlinux.lds.h: fixup HEADERED_SECTION{,_BY} macros
Posted by Jim Cromie 10 months, 1 week ago
commit 1d926e259d8f ("vmlinux.lds.h: add HEADERED_SECTION_* macros")

I flubbed the defn of the outer 2 macros; they missed the extra arg
needed: _front/_hdr.  Fix it now, before anyone notices.

I don't see any usage of this change in the series. Is it related to it? 
If no, can you make this a separate series, it is already difficult to 
review the dyndbg part without unrelated noise?
