I will fix this as well as address Andrew's and Joe's comments in a new patch. The only question is how to handle the overlap case: (a) abort the whole request or (b) try to reserve the part that overlaps (and adjust the request to avoid the overflow) I think (b) is more in line with the current implementation for reservations. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
