[PATCH v2 for v3.15 0/3] UBI: block: Support very large volumes

[Ezequiel Garcia]

Changes from v1:

  * Fixed ubiblock_resize so it returns something. I've kept a ubi_warn
    message in ubiblock_resize, because otherwise the failure is not reported
    to the user in any way.
    Thanks for the kbuild-robot for reporting this!

Here's the v1 cover letter:

This is a re-spin of Richard's work [1]. I've added a patch for some minor
clean-up, so the large volume fix is a less intrusive one.

The proposed returned value E2BIG has been changed for EFBIG, which results
in a slightly more accurate error. Also, the user messages have been removed
entirely; returning an error seems enough.

This bug was reported on #mtd IRC. I don't have to reporter name to give proper
credit. It should be applied as a fix for v3.15.

Richard: Thanks a lot for hunting this down, and feel free to disagree about
my changes.
