| |
Not that any of us who don't do embedded projects ought to care very much, but I was curious. I grepped test9pre6 for globals initialized to 0 or NULL and came up with 2495 lines, first iteration. At 4-byte alignment this works out to something over 9k of .data that should be .bss (not that anyone compiles very much of this in at a time).
A lot of recent Linus patches seem to have this conversion in them, so it seems someone *does* care about image size. (Presumably people running the kernel in-place from flash, right?) Would anyone be interested in patches to uninitialize these variables? I'd be willing to proofread my grep output.
(A related question: __initdata *does* have to be initialized, right?)
