[PATCH 2/2] ubi: Expose the bitrot interface

Using UBI_IOCRPEB and UBI_IOCSPEB userspace can force reading and scrubbing of PEBs. In case of bitflips UBI will automatically take action and move data to a different PEB. This interface allows a daemon to foster your NAND. Signed-off-by: Richard Weinberger --- drivers/mtd/ubi/cdev.c |
