    UBIFS: add debugfs knob to switch to R/O mode · 06bef945

    This patch adds another debugfs knob which switches UBIFS to R/O mode.
    I needed it while trying to reproduce the 'first log node is not CS node'
    bug. Without this debugfs knob you have to perform a power cut to repruduce
    the bug. The knob is named 'ro_error' and all it does is it sets the
    'ro_error' UBIFS flag which makes UBIFS disallow any further writes - even
    write-back will fail with -EROFS. Useful for debugging.
