* deadline-iosched: allow non-sequential batchingAaron Carroll2008-10-091-11/+3
| | | | | | | | | | | Deadline currently only batches sector-contiguous requests, so except for a few circumstances (e.g. requests in a single direction), it is essentially first come first served. This is bad for throughput, so change it to CSCAN, which means requests in a batch do not need to be sequential and are issued in increasing sector order.

* virtio_blk: use a wrapper function to access io context information of IO ↵Fernando Luis Vázquez Cao2008-10-092-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | requests struct request has an ioprio member but it is never updated because currently bios do not hold io context information. The implication of this is that virtio_blk ends up passing useless information to the backend driver. That said, some IO schedulers such as CFQ do store io context information in struct request, but use private members for that, which means that that information cannot be directly accessed in a IO scheduler-independent way. This patch adds a function to obtain the ioprio of a request. We should avoid accessing ioprio directly and use this function instead, so that its users do not have to care about future changes in block layer structures or what the currently active IO controller is. This patch does not introduce any functional changes but paves the way for future clean-ups and enhancements.

* Allow elevators to sort/merge discard requestsDavid Woodhouse2008-10-098-23/+42
| | | | | | | | | | | | | But blkdev_issue_discard() still emits requests which are interpreted as soft barriers, because naïve callers might otherwise issue subsequent writes to those same sectors, which might cross on the queue (if they're reallocated quickly enough). Callers still _can_ issue non-barrier discard requests, but they have to take care of queue ordering for themselves.

* Add BLKDISCARD ioctl to allow userspace to discard sectorsDavid Woodhouse2008-10-093-0/+78
| | | | | | | | | | | | We may well want mkfs tools to use this to mark the whole device as unwanted before they format it, for example. The ioctl takes a pair of uint64_ts, which are start offset and length in _bytes_. Although at the moment it might make sense for them both to be in 512-byte sectors, I don't want to limit the ABI to that.

* Add 'discard' request handlingDavid Woodhouse2008-10-096-11/+130
| | | | | | | | | | | | | | | | | | | | Some block devices benefit from a hint that they can forget the contents of certain sectors. Add basic support for this to the block core, along with a 'blkdev_issue_discard()' helper function which issues such requests. The caller doesn't get to provide an end_io functio, since blkdev_issue_discard() will automatically split the request up into multiple bios if appropriate. Neither does the function wait for completion -- it's expected that callers won't care about when, or even _if_, the request completes. It's only a hint to the device anyway. By definition, the file system doesn't _care_ about these sectors any more.

* SG_IO block filter whitelist missing MMC SET READ AHEAD commandxiphmont@xiph.org2008-10-091-0/+1
| | | | | | | | | | | | | | | | | | | | | I have another request for the block filter SG_IO command whitelist, specifically the MMC streaming command set SET READ AHEAD command. The command applies only to MMC CDROM/DVDROM drives with the streaming optional feature set. The command is useful to cdparanoia in that it allows explicit cache control side effects that are, on many drives, cdparanoia's most efficient way to flush/disable the media cache on cdrom drives. I am aware of no reason why it should not be accessible from usespace. Also note that the command is already fully accessible through the SCSI-native version of the SG_IO ioctl as well as the traditional SG interface. The command is only being refused on block devices. That means that on a typical stock distro, the command is available through /dev/sg* but not /dev/scd* although both are typically available and accessible. Filtering the command is not providing any protection, only a confusing inconsistency. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Benjamin Thery tracked down a bug that explains many instances of the error unregister_netdevice: waiting for %s to become free. Usage count = %d It turns out that netdev_run_todo can dead-lock with itself if a second instance of it is run in a thread that will then free a reference to the device waited on by the first instance. The problem is really quite silly. We were trying to create parallelism where none was required. As netdev_run_todo always follows a RTNL section, and that todo tasks can only be added with the RTNL held, by definition you should only need to wait for the very ones that you've added and be done with it. There is no need for a second mutex or spinlock. This is exactly what the following patch does. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Ali Saidi <saidi@engin.umich.edu> When TCP receive copy offload is enabled it's possible that tcp_rcv_established() will cause two acks to be sent for a single packet. In the case that a tcp_dma_early_copy() is successful, copied_early is set to true which causes tcp_cleanup_rbuf() to be called early which can send an ack. Further along in tcp_rcv_established(), __tcp_ack_snd_check() is called and will schedule a delayed ACK. If no packets are processed before the delayed ack timer expires the packet will be acked twice. Signed-off-by: David S. Miller <davem@davemloft.net>

When removing the promiscous flag from the VLAN device afterwards, the promiscous count on the real device is decremented a second time by the vlan_change_rx_flags() callback. The root cause for this is that the ->change_rx_flags() callback is invoked while the device is down. The synchronization is meant to mirror the behaviour of the ->set_rx_mode callbacks, meaning the ->open function is responsible for doing a full sync on open, the ->close() function is responsible for doing full cleanup on ->stop() and ->change_rx_flags() is meant to do incremental changes while the device is UP. Only invoke ->change_rx_flags() while the device is UP to provide the intended behaviour.

| * | | | IDE: Fix platform device registration in Swarm IDE driver (v2)Ralf Baechle2008-10-055-203/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Swarm IDE driver uses a release method which is defined in the driver itself thus potentially oopsable. The simple fix would be to just leak the device but this patch goes the full length and moves the entire handling of the platform device in the platform code and retains only the platform driver code in drivers/ide/mips/swarm.c.

| * | | | ide-dma: fix ide_build_dmatable() for TRM290Sergei Shtylylov2008-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently, 'xcount' being 0 does not mean 0 bytes for TRM290; it means 4 bytes, judging from the code immediately preceding this check. So, we must never try to "split" the PRD for TRM290. This is probably never hit anyway -- with the DMA buffers aligned to at least 512 bytes and ATAPI DMA not being used for non block I/O commands...
