    Hi,

    lock_super is currently implemented as follows:
            if (sb->s_lock)
                    __wait_on_super(sb);
            sb->s_lock ;

    Can this give rise to a race condition?

    I think using a semaphore for this purpose would be better.
    Or at least
               while(test_and_set_bit(1, &sb->s_lock))
                       __wait_on_super(sb);

    Regards.
