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/kernel/debug/moxtet/input
+Date: March 2019
+KernelVersion: 5.3
+Contact: Marek BehĂșn <kabel@kernel.org>
+Description: (Read) Read input from the shift registers, in hexadecimal.
+ Returns N+1 bytes, where N is the number of Moxtet connected
+ modules. The first byte is from the CPU board itself.
+
+ Example::
+
+ 101214
+
+ == =======================================
+ 10 CPU board with SD card
+ 12 2 = PCIe module, 1 = IRQ not active
+ 14 4 = Peridot module, 1 = IRQ not active

+Description: (RW) Read last written value to the shift registers, in
+ hexadecimal, or write values to the shift registers, also
+ in hexadecimal.
+
+ Example::
+
+ 0102
+
+ == ================================================
+ 01 01 was last written, or is to be written, to the
+ first module's shift register
+ 02 the same for second module
