Nack to this and nack to the problem patch, which is absolutely pointless and did nothing but introduce this error. readahead() is supposed to return 0, -EINVAL, or -EBADF and your original patch broke it. That's because your original patch was completely pointless to begin with. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
