After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).Signed-off-by: Tim Schmielau

Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.Signed-off-by: Arjan van de Ven

According to the Bulk-Only spec, usb-storage is supposed to use the
_first_ bulk-in and bulk-out endpoints it finds, not the _last_. And
while we're at it, we ought to test the direction of the interrupt
endpoint as well. This patch (as842) makes both changes.Signed-off-by: Alan Stern

Now that port status change notifications are interrupt-driven,
ehci-hcd needs to tell usbcore when a remote-wakeup resume operation
is finished -- we can no longer rely on the core to poll and find
out. This patch (as843) uses the root-hub status timer to force a
poll after the resume is complete.The patch also changes the test for detecting when the TDRSMDN resume
period has expired. It's necessary to use time_after_eq() instead of
time_after(), since the polling is triggered precisely by a timer.
The same change is made for TDRSTR reset expiration, for consistency.Signed-off-by: Alan Stern

Switch ehci-hcd to use the new polling scheme, which reports root
hub status changes via the interrupt handler, in an asynchronous
fashion. Doing so disables polling for status changes (whose handler is
rh_timer_func).Tested on a Geode GX machine, which is now capable of running at =~ 5
timer interrupts per second (in the -rt tree), resulting in significant
power savings.Signed-off-by: Marcelo Tosatti

This patch (as837) fixes several mistakes in the AIO interface of the
gadgetfs driver:The ki_retry method is not supposed to do a put on the kiocb.
The extra call to aio_put_req() causes memory corruption.
(Note: This call was removed before, by patch as691, and then
mysteriously re-introduced later.)Even if a read transfer is cancelled, we can and should send
to the user all the data that did manage to get transferred.Testing for AIO cancellation in the I/O completion handler
is both racy and (now) unnecessary. aio_complete() does its
own checking, in a safe manner.Signed-off-by: Alan Stern

This resolves a race in gadgetfs associated with changing device/ep0
when processing control requests. The fix is to change that state
earlier, when the control response is issued, so there's no window
in which userspace could see the wrong state; and enlarge the scope
of the spinlock during the ep0 request completion handler.Signed-off-by: David Brownell

This simplifies event reading by eliminating arithmetic and being

Minor gadgetfs cleanups:
- EP0 state constants become consistently STATE_DEV_* rather than
sometimes omitting the "DEV_"; STATE_EP_* were already consistent.- Comment that ep0 state is protected by the spinlock, and update
code that was neglecting that rule.None of this is expected to change behavior.
