[Qemu-devel] [PATCH 07/23] ide: also reset io_buffer_index for writes |

From: Christoph Hellwig <address@hidden>
Currenly the code only resets the io_buffer_index field for reads,
but the code seems to expect this for all types of I/O. I guess
we simply don't hit large enough transfers that would require this
often enough.
