    Subjectsilent semantic changes with reiser4
    After looking trough the code and mailinglists I'm quite unhappy with
    a bunch of user-visible changes that Hans sneaked in and make reiser4
    incompatible with other filesystems and have a slight potential to break
    even in the kernel.

    o files as directories
    - O_DIRECTORY opens succeed on all files on reiser4. Besides breaking
    .htaccess handling in apache and glibc compilation this also renders
    this flag entirely useless and opens up the races it tries to
    prevent against cmpletely useless
    - meaning of the -x permission. This one has different meanings on
    directories vs files on UNIX systems. If we want to support
    directories as files we'll probably have to find a way to work
    around this.
    - dentry aliasing. I can't find a formal guarantee in the code this
    can't happen

    o metafiles - ..metas as a magic name that's just taken out of the
    namespace doesn't sound like a good idea. If we want this it should
    be a VFS-level option and there should be a translation-layer to
    xattrs. Not doing this will again confuse applications greatly that
    expect uniform filesystem behaviour.

    Given these problems I request that these interfaces are removed from
    reiser4 for the kernel merge, and if added later at the proper VFS level
    after discussion on linux-kernel and linux-fsdevel, like we did for
    To unsubscribe from this list: send the line "unsubscribe linux-kernel" in
