I'm not sure this change is necessary. The code is inherited from kernel, I doubt that this would be wrong && unnoticed. PTR_ERR should be always used after IS_ERR, this does all the typecasts and checks, the final value is in the range of -MAX_ERRNO..0. MAX_ERRNO is 4095, even if long is wider than int, there is no loss.
Did you turn on some extra compiler warnings? david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
