    SubjectRe: [PATCH 01/11] IMA: use rbtree instead of radix tree for inode information cache

    I disagree. First off, this isn't actually true. Look at things like
    quota support: it eats more memory in the inode than IMA does after
    this patch-series (two pointers), and most people don't use that
    either. So the "it must use zero extra memory" is bogus - it's a
    balance between simplicity of the code and memory use.

    Secondly, right now we're in the situation that IMA just sucks. Sucks
    with all capital letters, in fact. This patch-series may not be
    perfect, but it's _so_ much better than the current situation that I
    don't really see why people are so adamantly negative about it.

    Please do feel free to be constructive about it, and I'm sure there
    are ways to improve even more, but right now "constructive" is not
    what the objections seem to be.
