This feature can reduce total interrupt overhead for RAID setups
in some situations, by deferring the interrupt signal until one or both of:
a) a specified io_count (completed SATA commands) is achieved, or
b) a specified time interval elapses after an IO completion.
For now, module parameters are used to set the irq_coalescing_io_count

The only way for a sysfs attribute to remove itself (without
deadlock) is to use the sysfs_schedule_callback() interface.
Vegard Nossum discovered that a poorly written sysfs ->store
callback can repeatedly schedule remove callbacks on the same
device over and over, e.g.
$ while true ; do echo 1 > /sys/devices/.../remove ; done
If the 'remove' attribute uses the sysfs_schedule_callback API
and also does not protect itself from concurrent accesses, its
callback handler will be called multiple times, and will
eventually attempt to perform operations on a freed kobject,
leading to many problems.
Instead of requiring all callers of sysfs_schedule_callback to
implement their own synchronization, provide the protection in
the infrastructure.
Now, sysfs_schedule_callback will only allow one scheduled
callback per kobject. On subsequent calls with the same kobject,
return -EAGAIN.
This is a short term fix. The long term fix is to allow sysfs
attributes to remove themselves directly, without any of this
callback hokey pokey.

from struct device, based on the following ideas:
1,Uevent sending should be one attribute of kobject, so suppressing it
in kobject layer is more natural than in device layer. By this way,
we can do it for other objects embedded with kobject.
2,It may save several bytes for each instance of struct device.(On my

which makes probe()/release()/... of platform_driver passed parameter
of platform_device *, so platform driver can get platform_data from
platform_device;
2. Other kind of devices do not need to use platform_data, we can
decrease size of device if moving it to platform_device.
Taking into consideration of thousands of files to be fixed and they
can't be finished in one night(maybe it will take a long time), so we
keep platform_data in device to allow two kind of cases coexist until
all platform devices pass its platfrom data from
platform_device->platform_data.

uioport is designed to be a setuid program and checks the permissions of

If a UIO device has several memory mappings, it can be difficult for userspace
to find the right one. The situation becomes even worse if the UIO driver can
handle different versions of a card that have different numbers of mappings.
Benedikt Spranger has such cards and pointed this out to me. Thanks, Bene!
To address this problem, this patch adds "name" sysfs attributes for each
mapping. Userspace can use these to clearly identify each mapping. The name
string is optional. If a driver doesn't set it, an empty string will be
returned, so this patch won't break existing drivers.
The same problem exists for port region information, so a "name" attribute is

Now platform_device is being widely used on SoC processors where the
peripherals are attached to the system bus, which is simple enough.
However, silicon IPs for these SoCs are usually shared heavily across
a family of processors, even products from different companies. This
makes the original simple driver name based matching insufficient, or
simply not straight-forward.
Introduce a module id table for platform devices, and makes it clear
that a platform driver is able to support some shared IP and handle
slight differences across different platforms (by 'driver_data').
Module alias is handled automatically when a MODULE_DEVICE_TABLE()
is defined.
To not disturb the current platform drivers too much, the matched id
entry is recorded and can be retrieved by platform_get_device_id().

The idea has been verified by the commit 6cd4958609,
which leads to a faster boot. But the commit 6cd4958609 has
the following drawbacks: 1),only does the quick check in
the path of __driver_attach->driver_probe_device, not in other
paths; 2),for a matched device and driver, check the same match
twice. It is a waste of cpu ,especially for some drivers with long
device id table (eg. usb-storage driver).
This patch adds a helper of driver_match_device to check the match

This ensures that both configurations can pass the USBCV remote

This patch (as1221) changes the way usbcore reinitializes a device
following a reset or a reset-resume. Currently we call
usb_set_interface() for every interface in the active configuration;
this is to put the interface into the same altsetting as before the
reset and to make sure that the host's endpoint state matches the
device's endpoint state.
However, sending a Set-Interface request is a waste of time if an
interface was already in altsetting 0 before the reset, since it is
certainly in altsetting 0 afterward. In addition, many devices can't
handle Set-Interface requests -- they crash when they receive them.
So instead, the patch adds code to check each interface. If the
interface wasn't in altsetting 0 before the reset, we go head with the
Set-Interface request as before. But if it was then we skip sending
the Set-Interface request, and we clear out the host-side endpoint
state by calling usb_disable_interface() followed by
usb_enable_interface().
The patch also adds a couple of new comments to explain what's going
on.

This patch fixes the following bug:
.plug ch341 usb serial port into a hub port;
.ch341 driver bound to the device and /dev/ttyUSB0 comes
.open /dev/ttyUSB0 by minicom and we can use the serial successfully
.suspend the ch341 usb serial device(such as: echo suspend > power/level)
.resume the ch341 usb serial device (such as: echo on > power/level)
.new port /dev/ttyUSB1 comes ,and the original /dev/ttyUSB0 still exists,
but is no longer usable by minicom
The patch adds suspend and resume callback to ch341 usb driver to prevent it
from unbinding during suspend. The /dev/ttyUSB0 is not released until being
closed, so /dev/ttyUSB1 comes after resume, and the original /dev/ttyUSB0 is
no longer usable by minicom. It is really a mess for a minicom user.
This patch also adds the reset_resume callback to make it usable after resuming
from STR or hibernation, for generally STR or hibernation will make the vbus
of root-hub lost.
Finally enable the driver's supports_autosuspend, for the device is in working
order with it.

Except on DaVinci, VBUS is now switched off as part of idling the
USB link (after a_wait_bcon) whenever a device is disconnected
from host. This is correct for OTG hosts, where either SRP or
an ID interrupt could turn VBUS on again.
However, for non-OTG hosts there's no way to turn VBUS on again,
so the host becomes unusable. And the procfs entry which once
allowed a manual workaround for this is now gone.
This patch adds an is_otg_enabled() check before scheduling the
switch-off timer in disconnect path, supporting a "classic host"
mode where SRP is unavailable.

Fixes endpoint starvation issue when more than one bulk QH is
multiplexed on the reserved bulk RX endpoint, which is normal
for cases like serial and ethernet adapters.
This patch sets the NAK timeout interval for such QHs, and when
a timeout triggers the next QH will be scheduled. (This resembles
the bulk scheduling done in hardware by EHCI, OHCI, and UHCI.)
This scheme doesn't work for devices which are connected to a
high to full speed tree (transaction translator) as there is
no NAK timeout interrupt from the musb controller from such
devices.
Tested with PIO, Inventra DMA, CPPI DMA.

This patch (as1206) is the first step in converting usb-storage's
subdrivers into separate modules. It makes the following large-scale
changes:
Remove a bunch of unnecessary #ifdef's from usb_usual.h.
Not truly necessary, but it does clean things up.
Move the USB device-ID table (which is duplicated between
libusual and usb-storage) into its own source file,
usual-tables.c, and arrange for this to be linked with
either libusual or usb-storage according to whether
USB_LIBUSUAL is configured.
Add to usual-tables.c a new usb_usual_ignore_device()
function to detect whether a particular device needs to be
managed by a subdriver and not by the standard handlers
in usb-storage.
Export a whole bunch of functions in usb-storage, renaming
some of them because their names don't already begin with
"usb_stor_". These functions will be needed by the new
subdriver modules.
Split usb-storage's probe routine into two functions.
The subdrivers will call the probe1 routine, then fill in
their transport and protocol settings, and then call the
probe2 routine.
Take the default cases and error checking out of
get_transport() and get_protocol(), which run during
probe1, and instead put a check for invalid transport
or protocol values into the probe2 function.
Add a new probe routine to be used for standard devices,
i.e., those that don't need a subdriver. This new routine
checks whether the device should be ignored (because it
should be handled by ub or by a subdriver), and if not,
calls the probe1 and probe2 functions.
