Subject: Merge tag 'ipe-pr-20260925' of
 git://git.kernel.org/pub/scm/linux/kernel/git/wufan/ipe

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
