usb: gadget: rename usb_gadget_driver::speed to max_speed This commit renames the “speed” field of the usb_gadget_driver structure to “max_speed”. This is so that to make it more apparent that the field represents the maximum speed gadget driver can support. This also make the field look more like fields with the same name in usb_gadget and usb_composite_driver structures. All of those represent the *maximal* speed given entity supports. After this commit, there are the following fields in various structures: * usb_gadget::speed - the current connection speed, * usb_gadget::max_speed - maximal speed UDC supports, * usb_gadget_driver::max_speed - maximal speed gadget driver supports, and * usb_composite_driver::max_speed - maximal speed composite gadget supports.

USB: gadgetfs: gadgetfs_disconnect: fix inconsistent lock state Under certain circumstances lockdep finds an inconsistent lock state in gadgetfs. The problem can be reproduced with a hardware using the ci13xxx_udc driver and the gadgetfs test program (needs a patch to support the ci13xxx_udc, though): http://www.linux-usb.org/gadget/usb.c Start the test program, wait to initialize, then press Ctrl+c.

usb: gadget: defer setting maxpacket till ->setup() maxpacket is set by the udc driver for ep0 very early. This value is copied by the function gadget used later for the USB_DT_DEVICE and USB_DT_DEVICE_QUALIFIER query. This seems to work fine so far. For USB3 we need set a different value here. In SS speed it is 2^x with x=9 and in HS we set something <= 64. If the UDC starts in SS and continues in HS after the cable has been plugged it will report a too small value. There setting of this value is defered and taken automaticly from the ep0 pointer where the UDC driver can update it according to the speed it detected _after_ a cable has been plugged.

usb: gadget: add usb_endpoint_descriptor to struct usb_ep Change usb_ep_enable() prototype to use endpoint descriptor from usb_ep. This optimization spares the FDs from saving the endpoint chosen descriptor. This optimization is not full though. To fully exploit this change, one needs to update all the UDCs as well since in the current implementation each of them saves the endpoint descriptor in it's internal (and extended) endpoint structure.

fs: do not assign default i_ino in new_inode Instead of always assigning an increasing inode number in new_inode move the call to assign it into those callers that actually need it. For now callers that need it is estimated conservatively, that is the call is added to all filesystems that do not assign an i_ino by themselves. For a few more filesystems we can avoid assigning any inode number given that they aren't user visible, and for others it could be done lazily when an inode number is actually needed, but that's left for later patches.

saner FASYNC handling on file close As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

USB: gadget: gadget_is_{dualspeed,otg} predicates and cleanup This adds two small inlines to the gadget stack, which will often evaluate to compile-time constants. That can help shrink object code and remove #ifdeffery. - gadget_is_dualspeed(), currently always a compile-time constant (depending on which controller is selected). - gadget_is_otg(), usually a compile time "false", but this is a runtime test if the platform enables OTG (since it's reasonable to populate boards with different USB sockets). It also updates two peripheral controller drivers to use these: - fsl_usb2_udc, mostly OTG-related bugfixes: non-OTG devices must follow the rules about drawing VBUS power, and OTG ones need to reject invalid SET_FEATURE requests. - omap_udc, just scrubbing a bit of #ifdeffery. And also gadgetfs, which lost some #ifdefs and moved to a more standard handling of DEBUG and VERBOSE_DEBUG. The main benefits come from patches which will follow.

usb gadget stack: remove usb_ep_*_buffer(), part 1 Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers. This patch just removes the interface and its users; later patches will remove controller driver support. - This interface is invariably not implemented correctly in the controller drivers (e.g. using dma pools, a mechanism which post-dates the interface by several years). - At this point no gadget driver really *needs* to use it. In current kernels, any driver that needs such a mechanism could allocate a dma pool themselves. Removing this interface is thus a simplification and improvement. Note that the gmidi.c driver had a bug in this area; fixed. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

USB: usb gadgets avoid le{16,32}_to_cpup() It turns out that le16_to_cpup() and le32_to_cpup() aren't always safe to call with pointers into packed structures, since those are inlined functions and GCC may lose the "packed" attribute. So those references can become unaligned kernel accesses, which are evil on some hardware. This patch updates uses of those routines in the gadget stack. The references into packed structures can just use leXX_to_cpu(*x), which in most cases is more natural. Some other uses in RNDIS, mostly in debug code, were wrong in the first place; those use get_unaligned().

USB: gadgetfs AIO tweaks This patch (as837) fixes several mistakes in the AIO interface of the gadgetfs driver: The ki_retry method is not supposed to do a put on the kiocb. The extra call to aio_put_req() causes memory corruption. (Note: This call was removed before, by patch as691, and then mysteriously re-introduced later.) Even if a read transfer is cancelled, we can and should send to the user all the data that did manage to get transferred. Testing for AIO cancellation in the I/O completion handler is both racy and (now) unnecessary. aio_complete() does its own checking, in a safe manner.

[PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_private The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

[PATCH] VFS: Permit filesystem to override root dentry on mount Extend the get_sb() filesystem operation to take an extra argument that permits the VFS to pass in the target vfsmount that defines the mountpoint. The filesystem is then required to manually set the superblock and root dentry pointers. For most filesystems, this should be done with simple_set_mnt() which will set the superblock pointer and then set the root dentry to the superblock's s_root (as per the old default behaviour). The get_sb() op now returns an integer as there's now no need to return the superblock pointer. This patch permits a superblock to be implicitly shared amongst several mount points, such as can be done with NFS to avoid potential inode aliasing. In such a case, simple_set_mnt() would not be called, and instead the mnt_root and mnt_sb would be set directly. The patch also makes the following changes: (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount pointer argument and return an integer, so most filesystems have to change very little. (*) If one of the convenience function is not used, then get_sb() should normally call simple_set_mnt() to instantiate the vfsmount. This will always return 0, and so can be tail-called from get_sb(). (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the dcache upon superblock destruction rather than shrink_dcache_anon(). This is required because the superblock may now have multiple trees that aren't actually bound to s_root, but that still need to be cleaned up. The currently called functions assume that the whole tree is rooted at s_root, and that anonymous dentries are not the roots of trees which results in dentries being left unculled. However, with the way NFS superblock sharing are currently set to be implemented, these assumptions are violated: the root of the filesystem is simply a dummy dentry and inode (the real inode for '/' may well be inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries with child trees. [*] Anonymous until discovered from another tree. (*) The documentation has been adjusted, including the additional bit of changing ext2_* into foo_* in the documentation.

[PATCH] USB: kzalloc() conversion in drivers/usb/gadget this patch converts drivers/usb to kzalloc usage. Compile tested with allyes config. I think there was a bug in drivers/usb/gadget/inode.c because it used sizeof(*data) for the kmalloc() and sizeof(data) for the memset(), since sizeof(data) just returns the size for a pointer.

[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_sem This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different. Modified-by: Ingo Molnar <mingo@elte.hu> (finished the conversion) Signed-off-by: Jes Sorensen <jes@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

[PATCH] USB: gadget driver updates (SETUP api change) This updates most of the gadget framework to expect SETUP packets use USB byteorder (matching the annotation in <linux/usb_ch9.h> and usage in the host side stack): - definition in <linux/usb_gadget.h> - gadget drivers: Ethernet/RNDIS, serial/ACM, file_storage, gadgetfs. - dummy_hcd It also includes some other similar changes as suggested by "sparse", which was used to detect byteorder bugs.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
