2009-04-02cgroup: fix frequent -EBUSY at rmdirKAMEZAWA Hiroyuki
In following situation, with memory subsystem, /groupA use_hierarchy==1 /01 some tasks /02 some tasks /03 some tasks /04 empty When tasks under 01/02/03 hit limit on /groupA, hierarchical reclaim is triggered and the kernel walks tree under groupA. In this case, rmdir /groupA/04 fails with -EBUSY frequently because of temporal refcnt from the kernel. In general. cgroup can be rmdir'd if there are no children groups and no tasks. Frequent fails of rmdir() is not useful to users. (And the reason for -EBUSY is unknown to users.....in most cases) This patch tries to modify above behavior, by - retries if css_refcnt is got by someone. - add "return value" to pre_destroy() and allows subsystem to say "we're really busy!"

2009-04-02gpio: gpio_{request,free}() now required (feature removal)David Brownell
We want to phase out the GPIO "autorequest" mechanism in gpiolib and require all callers to use gpio_request(). - Update feature-removal-schedule - Update the documentation now - Convert the relevant pr_warning() in gpiolib to a WARN() so folk using this mechanism get a noisy stack dump Some drivers and board init code will probably need to change. Implementations not using gpiolib will still be fine; they are already required to implement gpio_{request,free}() stubs.

2009-04-01fbdev: remove cyblafb driverKrzysztof Helt
A tridentfb driver has all the functionality of the cyblafb driver without the bugs of the latter. Changes to the tridentfb driver: - FBINFO_READS_FAST added to the tridentfb. The cyblafb used a blitter for scrolling which is faster than color expansion on Cyberblade chipsets. The blitter is slower on a discrete Blade3D core. Use the blitter for scrolling in the tridentfb only for integrated Blade3D cores. Now, scrolling speed is about equal for the tridentfb and the cyblafb. - a copyright notice addition is done on request of Jani Monoses (the first author of the tridentfb). Tested on AGP Blade3D card and PCChips M787CLR motherboard: VIA C3 cpu + VT8601 north bridge (aka Cyberblade/i1).

2009-04-01hwmon: Add LTC4215 driverIra Snyder
Add Linux support for the Linear Technology LTC4215 Hot Swap controller I2C monitoring interface. I have tested the driver with my board, and it appears to work fine. With the power supplies disabled, it reads 11.93V input, 1.93V output, no current and no power. With the supplies enabled, it reads 11.93V input, 11.98V output, no current, no power. I'm not drawing any current at the moment, so this is reasonable. The value in the sense register never reads anything except 0, so I expect to get zero from the current and power calculations. I didn't attempt to support changing any of the chip's settings or enabling the FET. I'm not sure even how to do that and still fit within the hwmon framework. :) Signed-off-by: Ira W.

2009-04-01filesystem freeze: allow SysRq emergency thaw to thaw frozen filesystemsEric Sandeen
Now that the filesystem freeze operation has been elevated to the VFS, and is just an ioctl away, some sort of safety net for unintentionally frozen root filesystems may be in order. The timeout thaw originally proposed did not get merged, but perhaps something like this would be useful in emergencies. For example, freeze /path/to/mountpoint may freeze your root filesystem if you forgot that you had that unmounted. I chose 'j' as the last remaining character other than 'h' which is sort of reserved for help (because help is generated on any unknown character). I've tested this on a non-root fs with multiple (nested) freezers, as well as on a system rendered unresponsive due to a frozen root fs.

2009-04-01mm: page_mkwrite change prototype to match faultNick Piggin
Change the page_mkwrite prototype to take a struct vm_fault, and return VM_FAULT_xxx flags. There should be no functional change. This makes it possible to return much more detailed error information to the VM (and also can provide more information eg. virtual_address to the driver, which might be important in some special cases). This is required for a subsequent fix. And will also make it easier to merge page_mkwrite() with fault() in future.

2009-03-31proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

set. Normally the parent device of v4l2_device is used as the video device node's parent. But if it was not set, then use the parent field in the video_device struct. This is needed in the cx88 driver, which has one core v4l2_device but creates multiple pci devices (one each for raw and mpeg video). So you cannot associate the core v4l2_device with a particular PCI device, but you can do that for each video_device.

The lock_norm module parameter doesn't look terribly useful. If you don't want to change the norm, just don't change it. As a matter of fact, no other v4l driver has such a parameter.

2009-03-30V4L/DVB (10827): Add support for GeoVision GV-800(S)Bruno Christo
I have a GeoVision GV-800(S) card, it has 4 CONEXANT BT878A chips. It has 16 video inputs and 4 audio inputs, and it is almost identical to the GV-800, as seen on http://bttv-gallery.de . The only difference appears to be the analog mux, it has a CD22M3494 in place of the MT8816AP. The card has a blue PCB, as seen in this picture: http://www.gsbr.com.br/imagem/kits/GeoVision%20GV%20800.jpg . This card wasn't originally supported, and it was detected as UNKNOWN/GENERIC. The video inputs weren't working, so I tried "forcing" a few cards like the GeoVision GV-600, but there was still no video. So I made a patch to support this card, based on the Kodicom 4400r. The GV-800(S) is identified as follows: ... 02:00.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 02:00.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) 02:04.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 02:04.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) 02:08.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 02:08.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) 02:0c.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 02:0c.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) ... 02:00.0 0400: 109e:036e (rev 11) Subsystem: 800a:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdfff000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 Kernel modules: bttv 02:00.1 0480: 109e:0878 (rev 11) Subsystem: 800a:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdffe000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 02:04.0 0400: 109e:036e (rev 11) Subsystem: 800b:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdffd000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 Kernel modules: bttv 02:04.1 0480: 109e:0878 (rev 11) Subsystem: 800b:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdffc000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 02:08.0 0400: 109e:036e (rev 11) Subsystem: 800c:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdffb000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 Kernel modules: bttv 02:08.1 0480: 109e:0878 (rev 11) Subsystem: 800c:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdffa000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 02:0c.0 0400: 109e:036e (rev 11) Subsystem: 800d:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdff9000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 Kernel modules: bttv 02:0c.1 0480: 109e:0878 (rev 11) Subsystem: 800d:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdff8000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 As you can see, the GV-800(S) card is almost identical to the GV-800 on bttv-gallery, so this patch might also work for that card. If not, only a few changes should be required on the gv800s_write() function. After this patch, the video inputs work correctly on linux 2.6.24 and 2.6.27 using the software 'motion'. The input order may seem a little odd, but it's the order the original software/driver uses, and I decided to keep that order to get the most out of the card. I tried to get the audio working with the snd-bt87x module, but I only get noise from every audio input, even after selecting a different mux with alsamixer. Also, after trying to play sound from those sources, I randomly get a RISC error about an invalid RISC opcode, and then that output stops working. I also can't change the sampling rate when recording. Any pointers to adding audio support are welcome.
