* elevator: make elevator_get() attempt to load the appropriate moduleJens Axboe2008-02-19
| | | | | | | | | | | | Currently we fail if someone requests a valid io scheduler, but it's modular and not currently loaded. That can happen from a driver init asking for a different scheduler, or online switching through sysfs as requested by a user. This patch makes elevator_get() request_module() to attempt to load the appropriate module, instead of requiring that done manually. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* cfq-iosched: add hlist for browsing parallel to the radix treeJens Axboe2008-02-19
| | | | | | | | | | | It's cumbersome to browse a radix tree from start to finish, especially since we modify keys when a process exits. So add a hlist for the single purpose of browsing over all known cfq_io_contexts, used for exit, io prio change, etc. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=9948 Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

The patch minimally reverts us back to the 2.6.19 code for a 2.6.20 release. <-- snip --> It has since been dead code, and unless someone wants to revive it now it's time to remove it. This patch also makes bio_release_pages() static again and removes the ki_bio_count member from struct kiocb, reverting changes that had been done for this dead code.

| * ide-cd: fix missing residual count setting in DMA modeKiyoshi Ueda2008-02-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the missing residual count setting in DMA mode, which was introduced during the conversion to blk-end-request. The residual count could be used by the request submitter. So if it isn't set correctly, some upper layers does not work. (e.g. wodim for CD burning.) The bug is in only DMA mode. In PIO mode, we are setting the residual count correctly, so no need to fix.

| * ht6560b: force prefetch for some devicesJan Evert van Grootheest2008-02-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prefetch needs to be set for some ide devices to work when connected to a ht6560b interface. This was not always done properly, causing a system with a HD and CD on the primary interface to not work properly. Or, in effect, hang hard. This patch forces prefetch on devices before checking whether it is necessary to change the settings in the interface This patch should also be applied to 2.4. I don't currently have a 2.4 tree around.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In nes_create_qp(), the test if (nesqp->mmap_sq_db_index > NES_MAX_USER_WQ_REGIONS) { is used to error out if the db_index is too large; however, if the test doesn't trigger, then the index is used as nes_ucontext->mmap_nesqp[nesqp->mmap_sq_db_index] = nesqp; and mmap_nesqp is declared as struct nes_qp *mmap_nesqp[NES_MAX_USER_WQ_REGIONS]; which leads to an array overrun if the index is exactly equal to NES_MAX_USER_WQ_REGIONS. Fix this by bailing out if the index is greater than or equal to NES_MAX_USER_WQ_REGIONS. This was spotted by the Coverity checker (CID 2162).

The kernel itself only needs _text to _end mapped in the high alias. On relocatible kernels the ASM setup code adjusts the compile time created high mappings to the relocation. This creates invalid pmd entries for negative offsets: 0xffffffff80000000 -> pmd entry: ffffffffff2001e3 It points outside of the physical address space and is marked present. This starts at the virtual address __START_KERNEL_map and goes up to the point where the first valid physical address (0x0) is mapped. Zap the mappings before _text and after _end right away in early boot. This removes also the invalid entries. Furthermore it simplifies the range check for high aliases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It currently isn't possible to open the frontend device of cx88-mpeg devices (DVB or Blackbird) multiple times concurrently. (for instance, to attach a signal monitoring tool while reading a stream, or to send a frequency change ioctl) This patch fixes that condition.

The version 1.0.6 is mainly influenced by Oliver Neukum. He found a lot of small issues, that are fixed with this patch now. For me the most interesting thing is, that it's now safer to use it on other architectures. The history for version 1.0.6 is: - fixed coverity checker warnings in *_usb_driver_disconnect - probe()/open() race by correct ordering in probe() - DMA coherency rules by separate allocation of all buffers - use of endianness macros - abuse of spinlock, replaced by mutex - racy handling of timer in disconnect, replaced by delayed_work - racy interruptible_sleep_on(), replaced with wait_event_interruptible() - handle signals in read() The driver is tested with all Debian/testing radio programs and rdsd. The patch is tested against checkpatch.pl v1.12. Signed-off-by: Tobias Lorenz <tobias.lorenz@gmx.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

However, isoc transfers require a large amount of data to be transfered. Before this patch, just one em28xx board were enough to allocate more than 50% URBs: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc=480/800 us (60%), #Int= 0, #Iso= 2 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 So, only one board could use an USB host at the same time. After the patch, it is possible to use more than one em28xx at the same time, on the same usb host, if the image size is slower or equal to 345600, since those images will require about 30% of the URBs: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc=232/800 us (29%), #Int= 0, #Iso= 2 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 So, in thesis, after the patch, it would be possible to use up to 3 boards by each usb host, if the devices are generating small images.
