I get the following error messages when trying to open a CD device
(specifically, the Teac CD-ROM CD-224E) that has no media present:

hda: packet command error: status=3D0x51 { DriveReady SeekComplete Error }
hda: packet command error: error=3D0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown

This happens when a "start stop unit" command (0x1b 0 0 0 3 0 0 0 0 0)
is sent to the drive to try to close the CD-ROM tray, but this drive
doesn't have that capability (it's a slim portable-type CD-ROM), so it
reports sense key 5 (illegal request) with asc/ascq 24/0.  This is
exactly how SFF8090i says it should respond.

But ide-cd.c (in cdrom_decode_status() ) just sees sense key 5 and spews
out an error.  It then goes on to request sense data, and
cdrom_log_sense() understands this error and doesn't log it.

The patch, for kernel 2.6.20.4, suppresses this error message.

It is possible for the timer expiry function to run even though the
request has already been handled: ide_timer_expiry() only checks that
the handler is not NULL, but it is possible that we have handled a
request (thus clearing the handler) and then started a new request
(thus starting the timer again, and setting a handler). 

A simple way to exhibit this is to set the DMA timeout to 1 jiffy and
run dd: The kernel will panic after a few minutes because
ide_timer_expiry() tries to add a timer when it's already active.

To fix this, we simply add a request generation count that gets
incremented at every interrupt, and check in ide_timer_expiry() that
we have not already handled a new interrupt before running the expiry
function.

For the cases that slow_start_after_idle are meant to deal
with, it is almost a certainty that the congestion window
tests will think the connection is application limited and
we'll thus decrease the cwnd there too.  This defeats the
whole point of setting slow_start_after_idle to zero.

So test it there too.

We do not cancel out the entire tcp_cwnd_validate() function
so that if the sysctl is changed we still have the validation
state maintained.

Nobody ported ffmpeg from dv1394 to rawiso yet, and there is no
justification to remove dv1394 right now.

Nevertheless, a strong deprecation of this ABI makes a lot of sense,
especially as Kristian H's drivers shape up to be an attractive
alternative to the existing ones.  But we don't have a schedule at the

Since lazy MMU batching mode still allows interrupts to enter, it is
possible for interrupt handlers to try to use kmap_atomic, which fails when
lazy mode is active, since the PTE update to highmem will be delayed.  The
best workaround is to issue an explicit flush in kmap_atomic_functions
case; this is the only way nested PTE updates can happen in the interrupt
handler.

Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

the p->parent PID printout gives us all the information about the

younger_sibling() printouts are mostly historic and i do not
remember ever having used those fields. (IMO in fact they confuse
the SysRq-T output.) So remove them.

This code has sentimental value though, those fields and
printouts are one of the oldest ones still surviving from
Linux v0.95's kernel/sched.c:

        if (p->p_ysptr || p->p_osptr)
                printk("   Younger sib=%d, older sib=%d\n\r",
                        p->p_ysptr ? p->p_ysptr->pid : -1,
