The srcu structure pointer array is modified at module load time because the
array is fixed up by the module loader at load-time with the final locations

believe it is not know what the values in the ptr array are. I believe same
is true for the tracepoint ptrs array.
Also it needs to be in a separate __tracepoint_ptrs so that this code works:
mod->tracepoints_ptrs = section_objs(info, "__tracepoints_ptrs",
Did I miss some point? Thanks,
But there's a lot of others too. Hmm, does this mean that the RO data
sections that are in modules are not set to RO?
There's a bunch of separate sections that are RO. Just look in
include/asm-generic/vmlinux.lds.h under the RO_DATA_SECTION() macro.
A lot of the sections saved in module.c:find_module_sections() are in
that RO_DATA when compiled as a builtin. Are they not RO when loaded via
