[PATCH] set_current_state() commentary
Explain the mysteries of set_current_state().
Quoth Linus:
The scheduler itself never needs the memory barrier at all.
The barrier is needed only if the user itself ends up testing some other
thing afterwards, ie if you have
set_process_state(TASK_INTERRUPTIBLE);
if (still_need_to_sleep())
schedule();
then the "still_need_to_sleep()" thing may test flags and wakeup events,
and then you _may_ want to (and often do) make sure that the write of
TASK_INTERRUPTIBLE is serialized wrt the reads of any wakeup data (since
the wakeup may have happened on another CPU).
So the comment is somewhat wrong. We don't really _care_ whether the state
propagates out to other CPU's since all of our actions are purely local,
and there is nothing we do that is conditional on any other CPU: we're
going to sleep unconditionally, and the scheduler only cares about _our_
state, not about somebody elses state.

[PATCH] open returns ENFILE but creates file anyway
When open(O_CREAT) is called and the error, ENFILE, is returned, the file
may be created anyway. This is counter intuitive, against the SUS V3
specification, and may cause applications to misbehave if they are not
coded correctly to handle this semantic. The SUS V3 specification
explicitly states "No files shall be created or modified if the function
returns -1.".
The error, ENFILE, is used to indicate the system wide open file table is
full and no more file structs can be allocated.
This is due to an ordering problem. The entry in the directory is created
before the file struct is allocated. If the allocation for the file struct
fails, then the system call must return an error, but the directory entry
was already created and can not be safely removed.
The solution to this situation is relatively easy. The file struct should
be allocated before the directory entry is created. If the allocation
fails, then the error can be returned directly. If the creation of the
directory entry fails, then the file struct can be easily freed.

[PATCH] usb: fix uss720 schedule with interrupts off
This patch fixes the long standing schedule with interrupts off problem
of the uss720 driver. The problem is caused by the parport layer calling
the save and restore methods within a write_lock_irqsave guarded region.
The fix is to issue the control transaction requests required by save
and restore asynchronously.

Fair points, thanks.
When connected over USB2, this device reports a nonsense
bInterfaceProtocol value 6 and doesn't work with usb-storage. When
connected over USB1, the device reports the correct bInterfaceProtocol

This is patch as550 from Alan Stern.
Apparently someone changed the SCSI core so that it no longer holds the

on that lock being held.
This patch reintroduces the host lock where needed and tries to clarify

code that clears the TIMED_OUT and ABORTING bitflags so that it executes
as soon as the timed-out command has completed (and while the host lock

[PATCH] USB: EHCI port tweaks
One change may improve some S1 or S3 resume cases, and the other
seems mostly to explain some strange state "lsusb" would show.
Two fixes:
- On resume, don't think about resuming any unpowered port, or
resetting any port with OWNER set to the OHCI/UHCI companion.
This will make some S1 and S3 resume scenarios work better.
- PORT_CSC was not being cleared correctly in ehci_hub_status_data.
This was visible at least through current versions of "lsusb",
and might have caused some other hub related strangeness.
The fix addresses all three write-to-clear bits, using the same
approach that UHCI happens to use: a mask of bits that are
cleared in most writes to that port status register.
Original patch seems to have been from from William.Morrow@amd.com

This is a driver for the USB touchpad which can be found on post-February 2005
Apple PowerBooks.
This driver is derived from Johannes Berg's appletrackpad driver [1],

* appletouch is a full kernel driver, no userspace program is necessary
* appletouch can be interfaced with the synaptics X11 driver[2], in order
to have touchpad acceleration, scrolling, two/three finger tap, etc.
This driver has been tested by the readers of the 'debian-powerpc' mailing
list for a few weeks now and I believe it is now ready for inclusion into the
mainline kernel.

Frank Arnold for further improvements, and Alex Harper for some additional

Fixes include some BE/LE issues and a get/put_dev bug in the previous

Other changes include a change of the module name from "sisusb" to
"sisusbvga". The previous one was too generic IMHO.
Please note that the patch also affects the Makefile in

Heavily tested, as usual. Please apply.
One thing though: I already prepared for removal of the "mode" field and
