    Hi!

    JFFS2 has known bug in GC leading to -ENOSPC upon file removal. Time
    ago I've sent a patch with detailed explanations of what is going on.
    Probably your case is the same.

    Here is the patch
    http://lists.infradead.org/pipermail/linux-mtd/2007-December/020091.html
    (though infradead mailing list archive is missing most of messages
    from this thread)

    And here are some details
