Thanks for the backport. I think there's a small issue: the selinux patch calls
backing_file_user_path() with a 'const struct file *', but in 6.12 that
accessor still takes a non-const file pointer, so the build produces
const-discard warnings.

The cleanest fix is to also include the upstream prerequisite:

  4e301d858af17a ("fs: constify file ptr in backing_file accessor helpers")
