OK, thanks.
I think I was misunderstanding the effect of "git log -- <path>"


When "-- include/asm-generic" is passed, 36d37f11f555 is hidden.


$ git log --oneline --author=Masahiro | grep include/asm-generic/export.h
0316e4b04e01 export.h: remove include/asm-generic/export.h
36d37f11f555 export.h: remove include/asm-generic/export.h


$ git log --oneline --author=Masahiro -- include/asm-generic/ | grep
include/asm-generic/export.h
0316e4b04e01 export.h: remove include/asm-generic/export.h



"man git-log" explains why:


<path>...
  Show only commits that are enough to explain how the files that match the
  specified paths came to be. See History Simplification below for details
  and other simplification modes.
