From 596bb44dead047249c11df24b0e1ffaa514f4909 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 20 Dec 2010 13:45:58 +0100 Subject: [PATCH] ide: also reset io_buffer_index for writes 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.
