That would be absolutely lovely for many other reasons as well, and we should also add a tool to tools/ to edit/expand/shrink those ELF notes on existing systems.

Linux binaries could carry capabilities information, etc. etc. Thanks, Ingo -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
