commit 41e8149c8892ed1962bd15350b3c3e6e90cba7f4 ] This adds a
Kconfig option and boot param to allow removing the FOLL_FORCE
flag from /proc/pid/mem write calls because it can be abused.
And this is not a mount option why?
Hello and thanks for asking!
The only reason is nobody asked for it yet. :)
We need to be careful how we do this, so the restriction is still
enabled when remounting, otherwise I don't see any impediment,
provided we can find a way to make it clean and safe.
I am travelling these weeks (All Systems GO conf) and have a lot
going on, so please feel free to send a patch and I'll review it
ASAP, otherwise I'll try to come up with something by end of
October.
