  • b403a98e2   block: improve automatic native capacity unlocking ... Browse Code »

    Currently, native capacity unlocking is initiated only when a
    recognized partition extends beyond the end of the disk. However,
    there are several other unhandled cases where truncated capacity can
    lead to misdetection of partitions.

    * Partition table is fully beyond EOD.

    * Partition table is partially beyond EOD (daisy chained ones).

    * Recognized partition starts beyond EOD.

    This patch updates generic partition check code such that all the
    above three cases are handled too. For the first two, @state tracks
    whether low level partition check code tried to read beyond EOD during
    partition scan and triggers native capacity unlocking accordingly.
    The third is now handled similarly to the original unlocking case.

  • 1493bf217   block: use struct parsed_partitions *state universally in partition check code ... Browse Code »

    Make the following changes to partition check code.

    * Add ->bdev to struct parsed_partitions.

    * Introduce read_part_sector() which is a simple wrapper around
    read_dev_sector() which takes struct parsed_partitions *state
    instead of @bdev.

    * For functions which used to take @state and @bdev, drop @bdev. For
    functions which used to take @bdev, replace it with @state.

    * While updating, drop superflous checks on NULL state/bdev in ldm.c.

    This cleans up the API a bit and enables better handling of IO errors
    during partition check as the generic partition check code now has
    much better visibility into what went wrong in the low level code
    paths.

  • 689d6fac4   block: replace @ext_minors with GENHD_FL_EXT_DEVT ... Browse Code »

    With previous changes, it's meaningless to limit the number of
    partitions. Replace @ext_minors with GENHD_FL_EXT_DEVT such that
    setting the flag allows the disk to have maximum number of allowed
    partitions (only limited by the number of entries in parsed_partitions
    as determined by MAX_PART constant).

    This kills not-too-pretty alloc_disk_ext[_node]() functions and makes
    @minors parameter to alloc_disk[_node]() unnecessary. The parameter
    is left alone to avoid disturbing the users.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
