Hi,
- BLKSSZGET added in common.h
Why don't we give BLKSSZGET a new number and make the old one obsolete? I
don't think it's used anywhere, as its result is pretty useless in
userspace (and even if it's used somewhere, they have to copy the define
anyway). This way we don't need that version

If you play hr eject an audio cd-rom from gtcd (a GNOME cd player), you

Correct. But the problem is that the page won't stay

No.

Does the following pseudocode do what I think it does?
Assume the semaphore is properly initialized to locked.
int flagvar = 0;
struct semaphore blocking_sem;
void function_called_from_kernel_thread(void)
{
chew_on_hardware();
flagvar = 1;
down(blocking_sem);

You have a race condition.
int flagvar = 0;
struct semaphore blocking_sem;
void function_called_from_kernel_thread(void)
{
chew_on_hardware();

As soon as you do/did this, the IRQ must've happened. So, before the next
statement is executed, the IRQ handler is

You know, it would help if I posted the right pseudocode.
Yes, I found this race condition a while ago. I do set flagvar _before_ I
chew on the hardware.
Nevertheless, what I'm seeing looks like either (a) the change to flagvar
isn't being propagated from the IRQ handler to the thread, or (b)
I will test this soon, hopefully. I move tomorrow, and will be bringing my
X environment and my audio environment into my dual P200 machine. This is
against which kernel? 2.4.0-test10 prepatch, or?
2.4.0-test9. It should work against a test10-preX.

Pinning using map_user_kiobuf looks just the other way around of what we do

But you see that one would need a new name as well,
otherwise the value associated with BLKSSZGET would
depend on the kernel version, and one would need

Hi James,
I think you missed to remove one restore_flags().
(There could be more, I only looked shortly at your patch)
Yeap. I didn't remove the restore_flag calls. Fixed now. Here is the
correct patch. I tested to see if it compiles against a test-9 kernel.
It does. That is the

Pinning happens every day on my box while I use rawio.
If you want to avoid pinning _userspace_ pages then we should delete
map_user_kiobuf and define a new functionality and API to replace RAWIO for
