I do not like this at all. It bloats the inode with three unsigned long values for a feature no sane person would ever use. And given that distros are sweet-talked by IBM to enable it the world will pay a huge penality for those 0.5% of the userbase that use IMA. Please reorder your series to have patch to disable IMA unless explicitly enabled on the kernel command line first, and then second use the rbtree from your last patch. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
