    Subject[28/74] UBIFS: do not read flash unnecessarily
    2.6.32-longterm review patch.  If anyone has any objections, please let us know.


    From: Artem Bityutskiy <>

    commit 8b229c76765816796eec7ccd428f03bd8de8b525 upstream.

    This fix makes the 'dbg_check_old_index()' function return
    immediately if debugging is disabled, instead of executing
    incorrect 'goto out' which causes UBIFS to:

    1. Allocate memory
    2. Read the flash

    On every commit. OK, we do not commit that often, but it is
    still silly to do unneeded I/O anyway.

    Credits to coverity for spotting this silly issue.
