This is a follow up on the V4 feedback:
https://lore.kernel.org/[email protected]
Changes vs. V4:
- Rename get/put_user_masked() to get/put_user_inline()
- Remove the futex helpers. Keep the inline get/put for now as it needs
more testing whether they are really valuable.
- Picked up tags
The series is based on v6.18-rc1 and also available from git:
git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git uaccess/scoped
move_addr_to_user() in net/socket.c and put_cmsg() in net/core/scm.c
should be converted as well

Thanks,
