Hi Petr,

Section .static_call_sites holds data structures that need to be sorted and
processed only at module load time. The section is never modified afterwards.
Make it therefore read-only after module initialization to avoid any
(non-)accidental modifications.
Petr Pavlu (3):
module: Constify parameters of module_enforce_rwx_sections()
module: Add a separate function to mark sections as read-only after
init
module: Make .static_call_sites read-only after init

We have a problem at the moment with ro_after_init sections, isn't it
better to fix it before adding new stuff to ro_after_init ?
This series conflicts with my series which aims at fixing up
ro_after_init handling in modules, see
https://patchwork.kernel.org/project/linux-modules/cover/cover.1733427536.git.christophe.leroy@xxxxxxxxxx/
I was expecting my series to land in modules-next, do you or Luis plan
to take it anytime soon ?
Christophe
