    Subject[PATCH v3 0/2] ubi: add possibility to skip CRC check for static UBI volumes
    Date
    Some users of static UBI volumes implement their own integrity check, thus
    making the volume CRC check done at open time useless. For instance, this
    is the case when one use the ubiblock + dm-verity + squashfs combination,
    where dm-verity already checks integrity of the block device but this time
    at the block granularity instead of verifying the whole volume.

    Skipping this test drastically improves the boot-time.

    Patches for mtd-utils will be available as well.

    Thanks,
    Quentin

    v3:
    - fix a few typos,

    v2:
    - use volume flags instead of arguments on the kernel command line as
    suggested by Richard,

    ubi: expose the volume CRC check skip flag
