From ef0f6a437f92fbd96c725086555b37b29371e107 Mon Sep 17 00:00:00 2001 From: Timothy Thelin Date: Fri, 16 Sep 2005 19:28:16 -0700 Subject: [PATCH] ide: fix null request pointer for taskfile ioctl When doing ioctl HDIO_DRIVE_TASKFILE, the ide_task_t's request pointer is never set, but flagged_taskfile and do_rw_taskfile pass it as a parameter to the prehandler. The kernel will oops taskfile pio-out commands because of this (taskfile pio-in doesn't use a prehandler). This fix sets the request pointer at the time the request is created to stop this oops.
