Device-mapper snapshot support
==============================
Device-mapper allows you, without massive data copying:
*) To create snapshots of any block device i.e. mountable, saved states of
the block device which are also writable without interfering with the
original content;
*) To create device "forks", i.e. multiple different versions of the
same data stream.
In both cases, dm copies only the chunks of data that get changed and
uses a separate copy-on-write (COW) block device for storage.
There are two dm targets available: snapshot and snapshot-origin.
*) snapshot-origin <origin>
which will normally have one or more snapshots based on it.
You must create the snapshot-origin device before you can create snapshots.
Reads will be mapped directly to the backing device. For each write, the
original data will be saved in the <COW device> of each snapshot to keep
its visible content unchanged, at least until the <COW device> fills up.
*) snapshot <origin> <COW device> <persistent?> <chunksize>
A snapshot is created of the <origin> block device. Changed chunks of
<chunksize> sectors will be stored on the <COW device>. Writes will
only go to the <COW device>. Reads will come from the <COW device> or
from <origin> for unchanged data. <COW device> will often be
smaller than the origin and if it fills up the snapshot will become
useless and be disabled, returning errors. So it is important to monitor
the amount of free space and expand the <COW device> before it fills up.
<persistent?> is P (Persistent) or N (Not persistent - will not survive
after reboot).
How this is used by LVM2
========================
When you create the first LVM2 snapshot of a volume, four dm devices are used:
1) a device containing the original mapping table of the source volume;
2) a device used as the <COW device>;
3) a "snapshot" device, combining #1 and #2, which is the visible snapshot
volume;
4) the "original" volume (which uses the device number used by the original
source volume), whose table is replaced by a "snapshot-origin" mapping
from device #1.
A fixed naming scheme is used, so with the following commands:
lvcreate -L 1G -n base volumeGroup
lvcreate -L 100M --snapshot -n snap volumeGroup/base
we'll have this situation (with volumes in above order):
# dmsetup table|grep volumeGroup
volumeGroup-base-real: 0 2097152 linear 8:19 384
volumeGroup-snap-cow: 0 204800 linear 8:19 2097536
volumeGroup-snap: 0 2097152 snapshot 254:11 254:12 P 16
volumeGroup-base: 0 2097152 snapshot-origin 254:11

For an URB which you've submitted, but which hasn't been returned to

There are two ways to cancel an URB you've submitted but which hasn't
been returned to your driver yet. For an asynchronous cancel, call
int usb_unlink_urb(struct urb *urb)

usb_unlink_urb() returns with that status code, you can free the URB

HW descriptors. The status is changed to reflect unlinking. Note
that the URB will not normally have finished when usb_unlink_urb()
returns; you must still wait for the completion handler to be called.
There is also an asynchronous unlink mode. To use this, set the
the URB_ASYNC_UNLINK flag in urb->transfer flags before calling
usb_unlink_urb(). When using async unlinking, the URB will not
normally be unlinked when usb_unlink_urb() returns. Instead, wait
for the completion handler to be called.
To cancel an URB synchronously, call
void usb_kill_urb(struct urb *urb)
It does everything usb_unlink_urb does, and in addition it waits
until after the URB has been returned and the completion handler
has finished. It also marks the URB as temporarily unusable, so
that if the completion handler or anyone else tries to resubmit it
they will get a -EPERM error. Thus you can be sure that when
usb_kill_urb() returns, the URB is totally idle.
1.7. What about the completion handler?
The handler is of the following type:
typedef void (*usb_complete_t)(struct urb *);
typedef void (*usb_complete_t)(struct urb *, struct pt_regs *)
i.e. it gets just the URB that caused the completion call.
I.e., it gets the URB that caused the completion call, plus the
register values at the time of the corresponding interrupt (if any).
In the completion handler, you should have a look at urb->status to
detect any USB errors. Since the context parameter is included in the URB,
you can pass information to the completion handler.

@ -229,24 +231,10 @@ ISO data with some other event stream.
Interrupt transfers, like isochronous transfers, are periodic, and happen
in intervals that are powers of two (1, 2, 4 etc) units. Units are frames
for full and low speed devices, and microframes for high speed ones.
Currently, after you submit one interrupt URB, that urb is owned by the
host controller driver until you cancel it with usb_unlink_urb(). You
may unlink interrupt urbs in their completion handlers, if you need to.
After a transfer completion is called, the URB is automagically resubmitted.
THIS BEHAVIOR IS EXPECTED TO BE REMOVED!!
Interrupt transfers may only send (or receive) the "maxpacket" value for
the given interrupt endpoint; if you need more data, you will need to
copy that data out of (or into) another buffer. Similarly, you can't
queue interrupt transfers.
THESE RESTRICTIONS ARE EXPECTED TO BE REMOVED!!
Note that this automagic resubmission model does make it awkward to use
interrupt OUT transfers. The portable solution involves unlinking those
OUT urbs after the data is transferred, and perhaps submitting a final
URB for a short packet.
The usb_submit_urb() call modifies urb->interval to the implemented interval
value that is less than or equal to the requested interval value.
In Linux 2.6, unlike earlier versions, interrupt URBs are not automagically
restarted when they complete. They end when the completion handler is
called, just like other URBs. If you want an interrupt URB to be restarted,
your completion handler must resubmit it.

This driver provides support for the IBM Hard Drive Active Protection
System (hdaps), which provides an accelerometer and other misc. data.
Supported laptops include the IBM ThinkPad T41, T42, T43, and R51.
The accelerometer data is readable via sysfs.
ThinkPads starting with the R50, T41, and X40 are supported. The
accelerometer data is readable via sysfs.
This driver also provides an input class device, allowing the
laptop to act as a pinball machine-esque mouse. This is off by
default but enabled via sysfs or the module parameter "mousedev".
This driver also provides an absolute input class device, allowing
the laptop to act as a pinball machine-esque joystick.
Say Y here if you have an applicable laptop and want to experience
the awesome power of hdaps.
