* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* i2c: Declare more i2c_adapter parent devicesJean Delvare2007-02-13
| | | | | | | | | | | | | | | Declare the parent device of i2c_adapter devices each time we can easily do so. It makes the i2c_adapter appear at the right place in the device tree, rather than as a platform device.

* [PATCH] mark struct file_operations const 3Arjan van de Ven2007-02-12
| | | | | | | | | | | Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

* ieee1394: fix host device registering when nodemgr disabledStefan Richter2007-02-08
| | | | | | | | | | | Since my commit 8252bbb1363b7fe963a3eb6f8a36da619a6f5a65 in 2.6.20-rc1, host devices have a dummy driver attached. Alas the driver was not registered before use if ieee1394 was loaded with disable_nodemgr=1. This resulted in non-functional FireWire drivers or kernel lockup. http://bugzilla.kernel.org/show_bug.cgi?id=7942 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* ieee1394: raw1394: prevent unloading of low-level driverStefan Richter2007-02-08
| | | | | | | | | | | | | | | Unloading the low-level driver module of a FireWire host can lead to all sorts of trouble if a raw1394 userspace client is using the host. Just disallow it by incrementing the LLD's module reference count on a RAW1394_REQ_SET_CARD write operation. Decrement it when the file is closed. This feature wouldn't be relevant if "modprobe -r video1394" or "modprobe -r dv1394" didn't automatically unload ohci1394 too. http://bugzilla.kernel.org/show_bug.cgi?id=7701 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Dan Dennedy <dan@dennedy.org>

* ieee1394: sbp2: lower block queue alignment requirementStefan Richter2007-02-08
| | | | | | | | | | | | | | | The old setting is copy & waste from usb-storage and doesn't apply to sbp2. There is only 4-byte alignment required for everything, except for S/G table elements which have to be 8-byte aligned according to the SBP-2 spec. (They happen to be ____cacheline_aligned in our implementation. Whether that's good is another question.) We now simply don't tune block queue alignment at all. The default alignment would surely never become anything else than a multiple of 4, else tons of calls to blk_queue_dma_alignment would have to be added everywhere in drivers/...

| | | | | | | | | | | | | | This patch applies a little change in csr1212.c to fix iSight (firewire digital camera) related issues (but maybe other firewire devices could also need such modification) The actual implementation of the "csr1212_key_id_type_map" table doesn't support some node types used by the iSight for the audio unit. This limit makes the csr scanning routine to never see the audio unit node , and consequently the iSight driver probe() routine to be never called and there is no way to hook an isight device when it is inserted.

* ieee1394: sbp2: fix probing of some DVD-ROM/RWsStefan Richter2007-01-10
| | | | | | | | | | | | | | | Since commit 98e238cd42be6c0852da519303cf0182690f8d9f in Linux 2.6.19, "ieee1394: sbp2: don't prefer MODE SENSE 10", some FireWire DVD-ROMs and DVD-RWs were mistaken as CD-ROM because sr_mod now sent MODE SENSE 6. The MMC command set includes only MODE SENSE 10. http://bugzilla.kernel.org/show_bug.cgi?id=7800 This fix lets sbp2 switch scsi_device.use_10_for_rw on for MMC LUs. This should rather be done in the command set driver sr_mod, not in the sbp2 transport driver, and an according patch will follow for a next Linux release.

| | | | | | | | | Follow-up to patch "Consolidate driver registering": Since I plan the lifetime of Linux 2.6.20 to be the deprecation phase of CONFIG_IEEE1394_EXPORT_FULL_API, it seems fair to keep all previously exported symbols available with this option until this phase is over.

* ieee1394: Consolidate driver registeringBen Collins2006-12-07
| | | | | | | | | | | | | This patch consolidates some bookkeeping for driver registering. It closely models what pci_register_driver() does. The main addition is that the owner of the driver is set, so we get a proper symlink for /sys/bus/ieee1394/driver/*/module. Also moves setting of name and bus type into nodemgr. Because of this, we can remove the EXPORT_SYMBOL for ieee1394_bus_type, since it's now only used in ieee1394.ko. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* ieee1394: nodemgr: fix deadlock in shutdownStefan Richter2006-12-07
| | | | | | | | | | | | | | | | | | | | | | If "modprobe ohci1394" was quickly followed by "modprobe -r ohci1394", say with 1 second pause in between, the modprobe -r got stuck in uninterruptible sleep in kthread_stop. At the same time the knodemgrd slept uninterruptibly in bus_rescan_devices_helper. That's because driver_detach took the semaphore of the PCI device and bus_rescan_devices_helper wanted to take the semaphore of the FireWire host device's parent, which is the same semaphore. This was a regression since Linux 2.6.16, commit bf74ad5bc41727d5f2f1c6bedb2c1fac394de731, "Hold the device's parent's lock during probe and remove". The fix (or workaround) adds a dummy driver to the hpsb_host device. Now bus_rescan_devices_helper won't scan the host device anymore. This doesn't hurt since we have no drivers which will bind to these devices and it is unlikely that there will ever be such a driver. The dummy driver is befittingly presented as a representation of ieee1394 itself. Fixes: http://bugzilla.kernel.org/show_bug.cgi?id=6706 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
