Subject: [patch V5 00/12] uaccess: Provide and use scopes for user access
Date: Mon, 27 Oct 2025 09:43:40 +0100 (CET) [thread overview]
Message-ID: <20251027083700.573016505@linutronix.de> (raw)
This is a follow up on the V4 feedback:
https://lore.kernel.org/20251022102427.400699796@linutronix.de
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
Thanks,
tglx
