Masatake YAMATO b42fa13311 ide: never called printk statement in ide-taskfile.c::wait_drive_not_busy
Look at wait_drive_not_busy in drivers/ide/ide-taskfile.c:

    static u8 wait_drive_not_busy(ide_drive_t *drive)
    {
            ide_hwif_t *hwif = HWIF(drive);
            int retries = 100;
            u8 stat;

            /*
             * Last sector was transfered, wait until drive is ready.
             * This can take up to 10 usec, but we will wait max 1 ms
             * (drive_cmd_intr() waits that long).
             */
            while (((stat = hwif->INB(IDE_STATUS_REG)) & BUSY_STAT) && retries--)
                    udelay(10);

            if (!retries)
                    printk(KERN_ERR "%s: drive still BUSY!\n", drive->name);

            return stat;
    }

`printk' is never called because `retries' never holds zero at the
outside of `while' loop: when `retries' holds zero at the while's loop
condition, `retries' will hold -1 at the if condition.

Alan Cox 3a42bb223f [PATCH] ide: add sanity checking to ide taskfile ioctl
Without this the user can feed in bogus values and get very bogus
results. Security impact is minimal as this ioctl isn't available to
unpriviledged processes anyway.

Reported to the l/k list and found with an auditing tool.

Jens Axboe 4aff5e2333 [PATCH] Split struct request ->flags into two parts
Right now ->flags is a bit of a mess: some are request types, and
others are just modifiers. Clean this up by splitting it into
->cmd_type and ->cmd_flags. This allows introduction of generic
Linux block message types, useful for sending generic Linux commands
to block devices.

Timothy Thelin ef0f6a437f [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.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
