simple_strtol returns signed, but a negative return values is lost when stored in an unsigned. As suggested use simple_strtoul() instead. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> --- Since p is dereferenced with the unsigned long return of simple_strtoul, I think p should be a pointer to an unsigned long, am I wrong? -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
