From 7eebe8a9c51686927709a57b1f2725d371014abc Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Fri, 6 Jan 2006 00:19:01 -0800 Subject: [PATCH] uml: umid cleanup This patch cleans up the umid code: - The only_if_set argument to get_umid is gone. - get_umid returns an empty string rather than NULL if there is no umid. - umid_is_random is gone since its users went away. - Some printfs were turned into printks because the code runs late enough that printk is working. - Error paths were cleaned up. - Some functions now return an error and let the caller print the error message rather than printing it themselves. This eliminates the practice of passing a pointer to printf or printk in, depending on where in the boot process we are. - Major tidying of not_dead_yet - mostly error path cleanup, plus a comment explaining why it doesn't react to errors the way you might expect. - Calls to os_* interfaces that were moved under os are changed back to their native libc forms. - snprintf, strlcpy, and their bounds-checking friends are used more often, replacing by-hand bounds checking in some places.
