Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull vfs updates from Al Viro: "The big thing in this pile is Eric's unmount-on-rmdir series; we finally have everything we need for that. The final piece of prereqs is delayed mntput() - now filesystem shutdown always happens on shallow stack. Other than that, we have several new primitives for iov_iter (Matt Wilcox, culled from his XIP-related series) pushing the conversion to ->read_iter()/ ->write_iter() a bit more, a bunch of fs/dcache.c cleanups and fixes (including the external name refcounting, which gives consistent behaviour of d_move() wrt procfs symlinks for long and short names alike) and assorted cleanups and fixes all over the place. This is just the first pile; there's a lot of stuff from various people that ought to go in this window.

Bluetooth: btmrvl: rename definitions from 88xx to 8897

Register offsets are different for SD8897 and newer chip SD8887. We can not have common btmrvl_sdio_card_reg map for them. Signed-off-by: Amitkumar Karwar Signed-off-by: Marcel Holtmann

Bluetooth: btusb: Implement driver internal packet reassembly

2014-09-16T18:33:15Z

When receiving USB interrupt, bulk or isochronous packet, they normally come in fragments. So far the driver just handed each fragment off to the hci_recv_fragment function of the Bluetooth core. That function is however so specific that is does not belong in the core. This patch implements the same reassembly logic in the driver. In addition this fixes a long standing bug where multiple complete packets are received within a single USB packet. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btusb: Split fragement receiption into separate functions

2014-09-16T03:41:17Z

The actual packet reassembly should be done inside the driver. To allow this to happen cleanly in future patches, split the fragment reception into its own functions. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btusb: Fix old coding style issues

2014-09-16T03:41:12Z

The btusb driver has been around for a while now and it is time to bring its coding style in sync with what has been done for the Bluetooth subsystem and other drivers. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btusb: Separate TX URB allocation and submission

2014-09-14T16:35:28Z

The complete TX URB handling is done via a switch statement in the btusb_send_frame function. To allow for more clear separation between control, bulk and isoc URBs, split them into allocation and submission. Previously the inc_tx function has been used for tracking in-flight URB for HCI commands and ACL data packets. Convert that into a common function that either submits the URB or queues it when needed. This provides the flexibility to allow vendor specific hdev->send_frame callbacks without having to duplicate the whole URB handling logic.

Bluetooth: btusb: Use GFP_KERNEL in btusb_send_frame()

2014-09-14T06:56:46Z

All hdev->send() calls are these days done through a work queue. For the btusb driver this means the btusb_send_frame() function. Because of this we can safely use GFP_KERNEL for all memory allocations in this code path. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann
