hook_modules_disabled($modules)Perform necessary actions after modules are disabled.
This function differs from hook_disable() as it gives all other modules a chance to perform actions when modules are disabled, whereas hook_disable() will only be called on the module actually being disabled.
$modules An array of the disabled modules.
