[PATCH 0/3] Add support for UBI and UBIFS

[Corentin Chary]

Hi,
Here is some patchs to add support for UBI and UBIFS in libblkid.

UBIFS works on top of UBI volumes, there are 3 subsystems involved:
  * MTD subsystem, which provides uniform interface to access flash chips.
    MTD provides an notion of MTD devices (e.g., /dev/mtd0) which basically represents raw flash;
  * UBI subsystem, which is a wear-leveling and volume management system for flash devices;
    UBI works on top of MTD devices and provides a notion of UBI volumes (e.g.m /dev/ubi0_0);
  * UBIFS file system, which works on top of UBI volumes.

The first patch add support for UBI volumes, which are represented as char devices in /dev/.
This allow to probe for UBIFS filesystem on UBI volumes.

Thanks,
