2011-03-22[media] v4l2: use new flag to enable core priority handlingHans Verkuil
Rather than guess which driver supports core priority handling, require drivers that do to explicitly set the V4L2_FL_USE_FH_PRIO flag in video_device. Updated the core prio handling accordingly and set the flag in the three drivers that do. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-03-22[media] ivtv: replace ugly casts with a proper container_ofHans Verkuil
ivtv-ioctl cast the 'void *fh' directly to 'ivtv_open_id *'. This should be done properly with a contained_of since the 'void *fh' is really a 'struct v4l2_fh *'. It worked because the v4l2_fh field is also the first field in the ivtv_open_id struct, but it is not clean code.

2011-03-22[media] v4l2-device: add kref and a release functionHans Verkuil
The video_device struct has proper ref counting and its release function will be called when the last user releases it. But no such support was available for struct v4l2_device. This made it hard to determine when a USB driver can release the device if it has multiple device nodes. With one device node it is easy of course, since when the device node is released, the whole device can be released. This patch adds refcounting to v4l2_device. When registering device nodes the v4l2_device refcount will be increased, when releasing device nodes it will be decreased. The (optional) release function will be called when the last device node was released. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-03-22[media] v4l2-fh: add v4l2_fh_is_singularHans Verkuil
Several drivers need to do something when the first filehandle is opened or the last filehandle is closed. Most implement some use count mechanism, but if they use v4l2_fh, then you can also just check if this is the only filehandle for the device node. A simple helper function can do this.

2011-03-22[media] saa7134-input: key up events not sent after suspend/resumeVadim Solomin
On my AverMedia AverTV Studio 507, key up events are no longer sent after a suspend-to-disk/resume cycle, resulting in "stuck" keys. Apparently, for key up events to be generated, a certain GPIO pin must be set. Currently it's set in saa7134_input_init1(), but that function is not called on device resume. I suggest that code be moved to __saa7134_ir_start(), which is called both on init and resume.

2011-03-22[media] via-camera: Fix OLPC serial checkDaniel Drake
The code that checks the OLPC serial port is never built at the moment, because CONFIG_OLPC_XO_1_5 doesn't exist and probably won't be added. Fix it so that it gets compiled in, only executes on OLPC laptops, and move the check into the probe routine. The compiler is smart enough to eliminate this code when CONFIG_OLPC=n (due to machine_is_olpc() always returning false).

2011-03-22libceph: add lingering request and watch/notify event frameworkYehuda Sadeh
Lingering requests are requests that are sent to the OSD normally but tracked also after we get a successful request. This keeps the OSD connection open and resends the original request if the object moves to another OSD. The OSD can then send notification messages back to us if another client initiates a notify. This framework will be used by RBD so that the client gets notification when a snapshot is created by another node or tool.

2011-03-22dmaengine/dmatest: Pass timeout via module paramsViresh Kumar
When we try to test all channels present on our controller together, some channels of lower priority may be very slow as compared to others. If number of transfers is unlimited, some channels may timeout and will not finish within 3 seconds. Thus, while doing such regress testing we may need to have higher value of timeouts. This patch adds support for passing timeout value via module parameters. Default value is 3 msec, a negative value means max timeout possible.

2011-03-22tracing: Fix set_ftrace_filter probe function displayJiri Olsa
If one or more function probes (like traceon) are enabled, and there's no other function filter, the first probe func is skipped (which one depends on the position in the hash). $ echo sys_open:traceon sys_close:traceon > ./set_ftrace_filter $ cat set_ftrace_filter #### all functions enabled #### sys_close:traceon:unlimited $ The reason was, that in the case of no other function filter, the func_pos was not properly updated before calling t_hash_start.

2011-03-22IB: Increase DMA max_segment_size on Mellanox hardwareDavid Dillow
By default, each device is assumed to be able only handle 64 KB chunks during DMA. By giving the segment size a larger value, the block layer will coalesce more S/G entries together for SRP, allowing larger requests with the same sg_tablesize setting. The block layer is the only direct user of it, though a few IOMMU drivers reference it as well for their *_map_sg coalescing code. pci-gart_64 on x86, and a smattering on on sparc, powerpc, and ia64. Since other IB protocols could potentially see larger segments with this, let's check those: - iSER is fine, because you limit your maximum request size to 512 KB, so we'll never overrun the page vector in struct iser_page_vec (128 entries currently). It is independent of the DMA segment size, and handles multi-page segments already. - IPoIB is fine, as it maps each page individually, and doesn't use ib_dma_map_sg(). - RDS appears to do the right thing and has no dependencies on DMA segment size, but I don't claim to have done a complete audit. - NFSoRDMA and 9p are OK -- they do not use ib_dma_map_sg(), so they doesn't care about the coalescing. - Lustre's ko2iblnd does not care about coalescing -- it properly walks the returned sg list. This patch ups the value on Mellanox hardware to 1 GB, which matches reported firmware limits on mlx4.
