Merge branch 'for-3.16/drivers' of git://git.kernel.dk/linux-block into next

2014-06-02T20:57:01Z

Pull block driver changes from Jens Axboe: "Now that the core bits are in, here's the pull request for the driver related changes for 3.16. Nothing out of the ordinary here, mostly business as usual. There are a few pulls of for-3.16/core into this branch, which were done when the blk-mq was modified after the mtip32xx conversion was put in. The pull request contains: - skd and cciss converted to use pci_enable_msix_exact(). From Alexander Gordeev. - A few mtip32xx fixes from Asai @ Micron. - The conversion of mtip32xx from make_request_fn to blk-mq, and a later small fix for that conversion on quiescing for non-queued IO. From me. - A fix for bsg to use an exported function to check whether this driver is request based or not. Needed updating for blk-mq, which is request based, but does not have a request_fn hook. From me. - Small floppy bug fix from Jiri. - A series of cleanups for the cdrom uniform layer from Joe Perches. Gets rid of various old ugly macros, making the code conform more to the modern coding style. - A series of patches for drbd from the drbd crew (Lars Ellenberg and Philipp Reisner). - A use-after-free fix for null_blk from Ming Lei. - Also from Ming Lei is a performance patch for virtio-blk, which can net us a 3x win on kvm platforms where world notification is expensive. - Ming Lei also fixed a stall issue in virtio-blk, due to a race between queue start/stop and resource limits. - A small batch of fixes for xen-blk{back,front} from Olaf Hering and Valentin Priescu" * 'for-3.16/drivers' of git://git.kernel.dk/linux-block: (54 commits) block: virtio_blk: don't hold spin lock during world switch xen-blkback: defer freeing blkif to avoid blocking xenwatch xen blkif.h: fix comment typo in discard-alignment xen/blkback: disable discard feature if requested by toolstack xen-blkfront: remove type check from blkfront_setup_discard floppy: do not corrupt bio.bi_flags when reading block 0 mtip32xx: move error handling to service thread virtio_blk: fix race between start and stop queue mtip32xx: stop block hardware queues before quiescing IO mtip32xx: blk_mq_init_queue() returns an ERR_PTR mtip32xx: convert to use blk-mq cdrom: Remove unnecessary prototype for cdrom_get_disc_info cdrom: Remove unnecessary prototype for cdrom_mrw_exit cdrom: Remove cdrom_count_tracks prototype cdrom: Remove cdrom_get_next_writeable prototype cdrom: Remove cdrom_get_last_written prototype cdrom: Move mmc_ioctls above cdrom_ioctl to remove unnecessary prototype cdrom: Remove unnecessary sanitize_format prototype cdrom: Remove unnecessary check_for_audio_disc prototype cdrom: Remove prototype for open_for_data ...

arm: xen: implement multicall hypercall support.

2014-04-24T12:09:46Z

As part of this make the usual change to xen_ulong_t in place of unsigned long. This change has no impact on x86. The Linux definition of struct multicall_entry.result differs from the Xen definition, I think for good reasons, and used a long rather than an unsigned long. Therefore introduce a xen_long_t, which is a long on x86 architectures and a signed 64-bit integer on ARM. Use uint32_t nr_calls on x86 for consistency with the ARM definition. Build tested on amd64 and i386 builds. Runtime tested on ARM. Signed-off-by: Ian Campbell Cc: Stefano Stabellini Cc: Konrad Rzeszutek Wilk Cc: Boris Ostrovsky Signed-off-by: David Vrabel

xen: add support for MSI message groups

2014-03-18T14:40:09Z

Add support for MSI message groups for Xen Dom0 using the MAP_PIRQ_TYPE_MULTI_MSI pirq map type. In order to keep track of which pirq is the first one in the group all pirqs in the MSI group except for the first one have the newly introduced PIRQ_MSI_GROUP flag set. This prevents calling PHYSDEVOP_unmap_pirq on them, since the unmap must be done with the first pirq in the group. Signed-off-by: Roger Pau Monné Signed-off-by: David Vrabel Cc: Boris Ostrovsky

Merge branch 'stable/for-jens-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip into for-linus

2014-02-10T19:52:34Z

Konrad writes: Please git pull the following branch: git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git stable/for-jens-3.14 which is based off v3.13-rc6. If you would like me to rebase it on a different branch/tag I would be more than happy to do so. The patches are all bug-fixes and hopefully can go in 3.14. They deal with xen-blkback shutdown and cause memory leaks as well as shutdown races. They should go to stable tree and if you are OK with I will ask them to backport those fixes. There is also a fix to xen-blkfront to deal with unexpected state transition. And lastly a fix to the header where it was using the __aligned__ unnecessarily.
