    Unfortunately linux-stable backported this:

      Subject: ima: Remove deprecated IMA_TRUSTED_KEYRING Kconfig

      From: Nayna Jain <nayna@linux.ibm.com>

      [ Upstream commit 5087fd9e80e539d2163accd045b73da64de7de95 ]

      Time to remove "IMA_TRUSTED_KEYRING".

    ...to all releases still being maintained.

    stable-queue$git grep -l 5087fd9e80e539
    releases/5.10.195/ima-remove-deprecated-ima_trusted_keyring-kconfig.patch
    releases/5.15.132/ima-remove-deprecated-ima_trusted_keyring-kconfig.patch
    releases/5.4.257/ima-remove-deprecated-ima_trusted_keyring-kconfig.patch
    releases/6.1.53/ima-remove-deprecated-ima_trusted_keyring-kconfig.patch
    releases/6.4.16/ima-remove-deprecated-ima_trusted_keyring-kconfig.patch
    releases/6.5.3/ima-remove-deprecated-ima_trusted_keyring-kconfig.patch

    So now when someone uses the feature, it triggers a do_kernel_configcheck
    warning when the audit runs.

    We added this file way back in 2019 so this fix will be needed on all
    active branches that are using an LTS linux-stable kernel listed above.
