here's some (good) text footprint data:
with the feature disabled (which is the default), the text size
difference with patch #1:
vmlinux:
text data bss dec hex filename
7732358 1157269 401408 9291035 8dc51b vmlinux.before
7732358 1157269 401408 9291035 8dc51b vmlinux.after
i.e. no overhead. Text size difference with patch #2:
vmlinux:
text data bss dec hex filename
7732358 1157269 401408 9291035 8dc51b vmlinux.before
7732374 1157269 401408 9291051 8dc52b vmlinux.after
16 bytes, or 0.0002% of the total text size. So there's in essence no
text overhead to talk about. So the text overhead argument is a red
herring.
