  • 8492b68bc   block: Remove integrity tagging functions ... Browse Code »

    None of the filesystems appear interested in using the integrity tagging
    feature. Potentially because very few storage devices actually permit
    using the application tag space.

    Remove the tagging functions.

  • 180b2f95d   block: Replace bi_integrity with bi_special ... Browse Code »

    For commands like REQ_COPY we need a way to pass extra information along
    with each bio. Like integrity metadata this information must be
    available at the bottom of the stack so bi_private does not suffice.

    Rename the existing bi_integrity field to bi_special and make it a union
    so we can have different bio extensions for each class of command.

    We previously used bi_integrity != NULL as a way to identify whether a
    bio had integrity metadata or not. Introduce a REQ_INTEGRITY to be the
    indicator now that bi_special can contain different things.

    In addition, bio_integrity(bio) will now return a pointer to the
    integrity payload (when applicable).

  • e7258c1a2   block: Get rid of bdev_integrity_enabled() ... Browse Code »

    bdev_integrity_enabled() is only used by bio_integrity_enabled().
    Combine these two functions.
