Pull IPE fixes from Fan Wu: "Two fixes for use-after-free issues found by recent LLM-assisted code analysis. - move successful policy load auditing under the new policy directory's inode lock, preventing a concurrent policy deletion from freeing the policy while it is still being audited - protect the dm-verity root hash with RCU, preventing policy evaluation from racing with root hash replacement during preresume" * tag 'ipe-pr-20260925' of git://git.kernel.org/pub/scm/linux/kernel/git/wufan/ipe: ipe: protect the dm-verity root hash with RCU ipe: fix use-after-free when auditing a newly loaded policy

+What: /sys/class/tee/tee{,priv}X/rpmb_routing_model
+Date: May 2024
+KernelVersion: 6.10
+Contact: op-tee@lists.trustedfirmware.org
+Description:
+ RPMB frames can be routed to the RPMB device via the
+ user-space daemon tee-supplicant or the RPMB subsystem
+ in the kernel. The value "user" means that the driver
+ will route the RPMB frames via user space. Conversely,
+ "kernel" means that the frames are routed via the RPMB
+ subsystem without assistance from tee-supplicant. It
+ should be assumed that RPMB frames are routed via user
+ space if the variable is absent. The primary purpose
+ of this variable is to let systemd know whether
+ tee-supplicant is needed in the early boot with initramfs.

+Contact: op-tee@lists.trustedfirmware.org
+Description:
+ Read-only revision string reported by the TEE driver. This is
+ for diagnostics only and must not be used to infer feature
+ support. Use TEE_IOC_VERSION for capability and compatibility
+ checks.
