Usually the usbmon returns the amount of data specified in
urb->transfer_buffer_length for output submissions and urb->actual_length
for input callbacks. However, for Isochronous input transfers, this is
not enough, since the returned data buffer may contain "holes".
One easy way to fix this is to use urb->transfer_buffer_length,
but this often transfers a whole lot of unused data, so we find
how much was actually used instead.

This patch (as1434) cleans up the uses of usb_mark_last_busy() in
usbcore. The function will be called when a device is resumed and
whenever a usage count is decremented. A call that was missing from
the hub driver is added: A hub is used whenever one of its ports gets
suspended (this prevents hubs from suspending immediately after their
last child).
In addition, the call to disable autosuspend support for new devices
by default is moved from usb_detect_quirks() (where it doesn't really
belong) into usb_new_device() along with all the other runtime-PM
initializations. Finally, an extra pm_runtime_get_noresume() is added
to prevent new devices from autosuspending while they are being
registered.

This patch (as1428) converts USB over to the new runtime-PM core
autosuspend framework. One slightly awkward aspect of the conversion
is that USB devices will now have two suspend-delay attributes: the
old power/autosuspend file and the new power/autosuspend_delay_ms
file. One expresses the delay time in seconds and the other in
milliseconds, but otherwise they do the same thing. The old attribute
can be deprecated and then removed eventually.

Since the runtime-PM core already defines a .last_busy field in

defined in usb_device and uses pm_runtime_mark_last_busy to implement

This commit fixes some issues with File-backed Storage Gadget
error recovery when registering LUN's devices.
First of all, when device_register() fails the device still
needs to be put. However, because lun_release() decreases
fsg->ref reference counter the counter must be incremented
beforehand.
Second of all, after any of the device_create_file()s fails,
device_unregister() is called which in turn (indirectly) calls
lun_release() which decrements fsg->ref. So, again, the
reference counter must be incremented beforehand.
Lastly, if the first or the second device_create_file()
succeeds, the files are never removed. To fix it,
device_remove_file() needs to be called. This is done by
simply marking LUN as registered prior to creating files so
that fsg_unbind() can handle removing files.

The only issue so far is that we could change the flp pointer even on an

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1)
As pointed out by Kerstin Jonsson <kerstin.jonsson@ericsson.com>, this
is due to CONFIG_32BIT not being defined, so the initramfs size field is
done as a 64-bit quad. On little-endian (like x86) this doesn matter,
but on a big-endian machine the 32-bit reads will see the (zero) high
bits.
Only mips, s390, and score set CONFIG_32BIT for 32-bit builds, so fix it for
all other 32-bit arches by inverting the logic and testing for CONFIG_64BIT,
which should be defined on all 64-bit arches.

The NFSv4 server was initializing the dp->dl_flock pointer by the
somewhat ridiculous method of a locks_copy_lock callback.
Now that setlease uses the passed-in lock instead of doing a copy,
dl_flock no longer gets set, resulting in the lock leaking on delegation
release, and later possible hangs (among other problems).
So, initialize dl_flock and get rid of the callback.
