The traditional way (eons ago) to deprecate something was to add a printk() and then delete the feature a few years later. Still, I have no objection to dropping that prctl. Sorry if I wasn't clear. I was objecting to the "language", i.e., to the word "deprecated." Deprecated means frowned on, advised against, etc. It does not mean "deleted." > printk(KERN_ERR "AUDIT_POSSIBLE is deprecated\n"); Yeah, that one's wrong also. :) -- ~Randy
