    Roman,

    I don't get this, you are arguing that we should put it in because it
    doesn't do any damage. First of all it does, by adding a lot of clutter
    all over the place. Second, if we take that argument, then we should
    allow anybody to put in anything they want, are you also suggesting we
    put devfs back in?

    Point is that the Linux kernel gets so many proposals, some are good
    some are bad and some while maybe looking like a good idea at the
    beginning, show out later to be a bad idea - LTT falls into this
    category. *However*, it doesn't mean the knowledge and tools that were
    developed with LTT are bad or useless.

    To take another related project, look at relayfs. There was so much
    noise about it when it was initially pushed, yuck I even remember how it
    was suggested that printk should be implemented via relayfs. But look at
    it now, there is no fs/relayfs/* these days. The kernel moved on, used
    the knowledge optained and provided the feature in a better way -
    exactly like it is being proposed to do for trace points, by using
    dynamic probes.
