[GIT PULL] selinux/selinux-pr-20260919

[Paul Moore]

Linus,

Three fixes for Linux v7.3-rcX:

- Ensure that the cached SELinux access decisions are correct.

- Fix the SELinux overlayfs code to properly track the top-level/user
information on multiple stacked overlayfs filesystems.

- Fix the SELinux overlayfs code to properly enforce mprotect() access
control policy on all of the different layers in multiple stacked
overlayfs filesystems.
