This patch changes loopback, usb-gadget, vhost-scsi and xen-scsiback
fabric code to invoke transport_register_session() instead of the
unprotected flavour, to ensure se_tpg->session_lock is taken when
adding new session list nodes to se_tpg->tpg_sess_list.
Note that since these four fabric drivers already hold their own
internal TPG mutexes when accessing se_tpg->tpg_sess_list, and
consist of a single se_session created through configfs attribute
access, no list corruption can currently occur.
So for correctness sake, go ahead and use the se_tpg->session_lock
protected version for these four fabric drivers.

Most callers in the kernel want to perform synchronous file I/O, but
still have to bloat the stack with a full struct kiocb. Split out
the parts needed in filesystem code from those in the aio code, and
only allocate those needed to pass down argument on the stack. The
aio code embedds the generic iocb in the one it allocates and can
easily get back to it by using container_of.
Also add a ->ki_complete method to struct kiocb, this is used to call
into the aio code and thus removes the dependency on aio for filesystems
impementing asynchronous operations. It will also allow other callers
to substitute their own completion callback.
We also add a new ->ki_flags field to work around the nasty layering
violation recently introduced in commit 5e33f6 ("usb: gadget: ffs: add
eventfd notification about ffs events").

That commit creates a problem for some UDCs (at least musb)
where it allocates an endpoints with a 64-byte FIFO, but later
tries to use that same FIFO for 1024-byte packets.
Before implementing this, composite framework needs to be
modified so we only allocate endpoints after we know negotiated
speed, however that needs quite a bit of extra work.

struct printer_dev contains 3 list heads: tx_reqs, rx_reqs and rx_buffers.
There is just one instance of this structure in the driver and it is
file static, and as such initialized with all zeros.
If device_create() or cdev_add() fails then "goto fail" branch is taken,
which results in printer_cfg_unbind() call. The latter checks if
tx_reqs, rx_reqs and rx_buffers lists are empty. The check for emptiness
is in fact a check whether the "next" member of struct list_head points
to the head of the list. But the heads of the lists in question have
not been initialized yet and, as mentioned above, contain all zeros,
so list_empty() returns false and respective "while" loop body starts
executing. Here, container_of() just subtracts the offset of a struct
usb_request member from an address of this same member, which results in
a value somewhere near 0 or 0xfff...ff. And the argument to list_del()
dereferences such a pointer which causes a disaster.
This patch moves respective INIT_LIST_HEAD() invocations to a point before
"goto fail" branch can be taken.

Function-specific setup requests should be handled in such a way, that
apart from filling in the data buffer, the requests are also actually
enqueued: if function-specific setup is called from composte_setup(),
the "usb_ep_queue()" block of code in composite_setup() is skipped.
The printer function lacks this part and it results in e.g. get device id
requests failing: the host expects some response, the device prepares it
but does not equeue it for sending to the host, so the host finally asserts
timeout.
This patch adds enqueueing the prepared responses.

Final methods start with get_ready_ep(), which will fail unless we have
->state == STATE_EP_ENABLED. So they'd be failing just fine until that
first write() anyway. Let's do the following:
* get_ready_ep() gets a new argument - true when called from
ep_write_iter(), false otherwise.
* make it quiet when it finds STATE_EP_READY (no printk, that is;
the case won't be impossible after that change).
* when that new argument is true, treat STATE_EP_READY the same
way as STATE_EP_ENABLED (i.e. return zero and do not unlock).
* in ep_write_iter(), after success of get_ready_ep() turn
if (!usb_endpoint_dir_in(&epdata->desc)) {
into
if (epdata->state == STATE_EP_ENABLED &&
!usb_endpoint_dir_in(&epdata->desc)) {
- that logics only applies after config.
* have ep_config() take kernel-side buffer (i.e. use memcpy()
instead of copy_from_user() in there) and in the "let's call ep_io or
ep_aio" (again, in ep_write_iter()) add "... or ep_config() in case it's

Merge tag 'usb-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB updates from Greg KH:
"Here's the big set of USB and PHY patches for 3.19-rc1.
The normal churn in the USB gadget area is in here, as well as xhci
and other individual USB driver updates. The PHY tree is also in
here, as there were dependancies on the USB tree.
All of these have been in linux-next"

SPC-3 defines SERVICE ACTION IN(12) and SERVICE ACTION IN(16).
So rename SERVICE_ACTION_IN to SERVICE_ACTION_IN_16 to be
consistent with SPC and to allow for better distinction.
