The unused bit mask was subsequently removed by commit 11c60f23ed13 ("integrity: Remove unused macro IMA_ACTION_RULE_FLAGS"). Restore the performance improvement by introducing the new mask IMA_NONACTION_RULE_FLAGS, equal to IMA_NONACTION_FLAGS without IMA_NEW_FILE, which is not a rule-specific flag. Finally, reset IMA_NONACTION_RULE_FLAGS instead of IMA_NONACTION_FLAGS in process_measurement(), if the IMA_CHANGE_ATTR atomic flag is set (after file metadata modification). With this patch, new files for which metadata were modified while they are still open, can be reopened before the last file close (when security.ima is written), since the IMA_NEW_FILE flag is not cleared anymore. Otherwise, appraisal fails because security.ima is missing (files with IMA_NEW_FILE set are an exception).
