    procfs: Push down the bkl from ioctl · d79b6f4d
    Frederic Weisbecker authored
    Push down the bkl from procfs's ioctl main handler to its users.
    Only three procfs users implement an ioctl (non unlocked) handler.
    Turn them into unlocked_ioctl and push down the Devil inside.
    
    v2: PDE(inode)->data doesn't need to be under bkl
    v3: And don't forget to git-add the result
    v4: Use wrappers to pushdown instead of an invasive and error prone
        handlers surgery.
