Hi Amerigo,
This looks wrong. The extable covers both init and core exception entries.
We want to remove the ones in the module_init section. The good news is that
it's sorted, so they're either at the start or the end (except sparc 32).
Hi, Rusty.
Yes? The extable of a module is in '__ex_table' section, and during the
section transfer, one
section will be either in module_init or module_core, so its entries are
only in one of them,
not both, right?
Thank you.
