Date: January 2008
KernelVersion: 2.6.25
Contact: Sarah Sharp <sarah.a.sharp@intel.com>
Description:
If CONFIG_PM and CONFIG_USB_SUSPEND are enabled, then this file
is present. When read, it returns the total time (in msec)
that the USB device has been active, i.e. not in a suspended
state. This file is read-only.

Tools can use this file and the connected_duration file to
compute the percentage of time that a device has been active.
For example,
echo $((100 * `cat active_duration` / `cat connected_duration`))
will give an integer percentage. Note that this does not
account for counter wrap.

What: USB driver API moves to EXPORT_SYMBOL_GPL
When: February 2008
Files: include/linux/usb.h, drivers/usb/core/driver.c
Why: The USB subsystem has changed a lot over time, and it has been
possible to create userspace USB drivers using usbfs/libusb/gadgetfs
that operate as fast as the USB bus allows. Because of this, the USB
subsystem will not be allowing closed source kernel drivers to
register with it, after this grace period is over. If anyone needs
any help in converting their closed source drivers over to use the
userspace filesystems, please contact the
linux-usb-devel@lists.sourceforge.net mailing list, and the developers
there will be glad to help you out.

What: vm_ops.nopage
When: Soon, provided in-kernel callers have been converted
Why: This interface is replaced by vm_ops.fault, but it has been around

audit_argv_kb
-------------

The file contains a single value denoting the limit on the argv array size
for execve (in KiB). This limit is only applied when system call auditing for
execve is enabled, otherwise the value is ignored.
