Let's make it clearer that functionality provided by FOLL_FORCE is really only for ptrace access. Prevent accidental re-use in drivers by renaming FOLL_FORCE to FOLL_PTRACE: git grep -l 'FOLL_FORCE' | xargs sed -i 's/FOLL_FORCE/FOLL_PTRACE/g' In the future, we might want to use a separate set of flags for the access_vm interface: most FOLL_* flags don't apply and we mostly only want to pass FOLL_PTRACE and FOLL_WRITE.
