Hi,
As discussed on lkml before; the patch with the infrastructure to deprecate unused symbols
This is patch one in a series of 17; to not overload lkml the other 16 will be mailed direct;
people who want to see them all can see them at http://www.fenrus.org/unused
This patch temporarily adds EXPORT_UNUSED_SYMBOL and EXPORT_UNUSED_SYMBOL_GPL.
These will be used as transition measure for symbols that aren't used in the kernel and are on the way out. When a module uses such a symbol, a warning
is printk'd at modprobe time.
The main reason for removing unused exports is size: eacho export takes roughly
between 100 and 150 bytes of kernel space in the binary. This patch gives
users the option to immediately get this size gain via a config option.
Do the exports take any space at runtime in RAM?
scsi patch comments (only one that I have seen) say:
+EXPORT_UNUSED_SYMBOL(scsi_print_status); /* removal in 2.6.19 */
and When: above says "before 2.6.19". Those don't agree.
Please fix. Thanks.
