compatibility Converting ecm to the new function interface requires converting the USB ecm's function code and its users. This patch converts the f_ecm.c to the new function interface. The file is now compiled into a separate usb_f_ecm.ko module. The old function interface is provided by means of a preprocessor conditional directives. After all users are converted, the old interface can be removed.

2013-06-10usb: gadget: u_ether: convert into moduleAndrzej Pietrasiewicz10-52/+98
u_ether.c has been #include'd by all gadgets which implement USB Ethernet functions. In order to add configfs support, the f_ecm.c, f_eem.c, f_ncm.c, f_subset.c, f_rndis.c need to be converted into modules and must not be #include'd. Consequently, the u_ether.c needs to be a module too, in a manner similar to u_serial.c. The resulting module should not take any parameters, so they are pushed to the current users of it, that is ether.c, g_ffs.c, multi.c, ncm.c, nokia.c.

2013-06-10usb: gadget: r8a66597-udc: do not unlock unheld spinlock in ↵Alexey Khoroshilov1-2/+2
r8a66597_sudmac_irq() r8a66597_irq() processes sudmac part (r8a66597_sudmac_irq()) before locking r8a66597->lock. But transfer_complete(), that is called inside (r8a66597_sudmac_irq()->sudmac_finish()->transfer_complete()), expects r8a66597->lock is locked. As a result unheld spinlock can be unlocked. The patch just moves locking before calling r8a66597_sudmac_irq(). Found by Linux Driver Verification project (linuxtesting.org).

2013-05-08aio: use cancellation list lazilyKent Overstreet1-2/+1
Cancelling kiocbs requires adding them to a per kioctx linked list, which is one of the few things we need to take the kioctx lock for in the fast path. But most kiocbs can't be cancelled - so if we just do this lazily, we can avoid quite a bit of locking overhead. While we're at it, instead of using a flag bit switch to using ki_cancel itself to indicate that a kiocb has been cancelled/completed. This lets us get rid of ki_flags entirely.

2013-05-08gadget: remove only user of aio retryZach Brown1-9/+29
This removes the only in-tree user of aio retry. This will let us remove the retry code from the aio core. Removing retry is relatively easy as the USB gadget wasn't using it to retry IOs at all. It always fully submitted the IO in the context of the initial io_submit() call. It only used the AIO retry facility to get the submitter's mm context for copying the result of a read back to user space. This is easy to implement with use_mm() and a work struct, much like kvm does with async_pf_execute() for get_user_pages().
