292  rc等于integrity_modsig_verify(INTEGRITY_KEYRING_IMA, modsig)
293  如果IS_ENABLED(CONFIG_FOO) evaluates to 1 if CONFIG_FOO is set to 'y' or 'm',* 0 otherwise.(CONFIG_INTEGRITY_PLATFORM_KEYRING)且rc且func恒等于KEXEC_KERNEL_CHECK则rc等于integrity_modsig_verify(INTEGRITY_KEYRING_PLATFORM, modsig)
297  如果rc则
298  cause等于"invalid-signature"
299  status等于INTEGRITY_FAIL
300  否则
301  status等于INTEGRITY_PASS
304  返回:rc
