i built GENERIC (including modules) with and without that flag. the results
are:
The same as it has always been. It avoids some bloat.
1654496 bytes with the flag set
vs.
1654952 bytes with the flag unset
I don't believe this. GENERIC is enormously bloated, so it has size
more like 16MB than 1.6MB. Even a savings of 4K instead of 456 bytes
i'm sorry. i used du(1) to get those numbers, so i believe those numbers
represent the ammount of 512-byte blocks. if i'm correct GENERIC is even
more bloated than you feared and almost reaches 1GB:
807,859375 megabytes with flag set
vs.
808,0820313 megabytes without the flag set
That's certainly bloated. It counts all object files and modules, and
probably everything is compiled with -g. I only counted kernel text
size.
