  • e66ecd505   [SCSI] target: Convert TASK_ATTR to scsi_tcq.h definitions ... Browse Code »

    This patch converts target core and follwing scsi-misc upstream fabric
    modules to use include/scsi/scsi_tcq.h includes for SIMPLE, HEAD_OF_QUEUE
    and ORDERED SCSI tasks instead of scsi/libsas.h with TASK_ATTR*

    *) tcm_loop: Convert tcm_loop_allocate_core_cmd() + tcm_loop_device_reset() to
    scsi_tcq.h
    *) tcm_fc: Convert ft_send_cmd() from FCP_PTA_* to scsi_tcq.h

  • 9cbbdca44   block: remove spurious uses of REQ_HARDBARRIER ... Browse Code »

    REQ_HARDBARRIER is deprecated. Remove spurious uses in the following
    users. Please note that other than osdblk, all other uses were
    already spurious before deprecation.

    * osdblk: osdblk_rq_fn() won't receive any request with
    REQ_HARDBARRIER set. Remove the test for it.

    * pktcdvd: use of REQ_HARDBARRIER in pkt_generic_packet() doesn't mean
    anything. Removed.

    * aic7xxx_old: Setting MSG_ORDERED_Q_TAG on REQ_HARDBARRIER is
    spurious. Removed.

    * sas_scsi_host: Setting TASK_ATTR_ORDERED on REQ_HARDBARRIER is
    spurious. Removed.

    * scsi_tcq: The ordered tag path wasn't being used anyway. Removed.

  • 9361401eb   [PATCH] BLOCK: Make it possible to disable the block layer [try #6] ... Browse Code »

    Make it possible to disable the block layer. Not all embedded devices require
    it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require
    the block layer to be present.

    This patch does the following:

    (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev
    support.

    (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls
    an item that uses the block layer. This includes:

    (*) Block I/O tracing.

    (*) Disk partition code.

    (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS.

    (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the
    block layer to do scheduling. Some drivers that use SCSI facilities -
    such as USB storage - end up disabled indirectly from this.

    (*) Various block-based device drivers, such as IDE and the old CDROM
    drivers.

    (*) MTD blockdev handling and FTL.

    (*) JFFS - which uses set_bdev_super(), something it could avoid doing by
    taking a leaf out of JFFS2's book.

    (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and
    linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is,
    however, still used in places, and so is still available.

    (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and
    parts of linux/fs.h.

    (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.

    (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.

    (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK
    is not enabled.

    (*) fs/no-block.c is created to hold out-of-line stubs and things that are
    required when CONFIG_BLOCK is not set:

    (*) Default blockdev file operations (to give error ENODEV on opening).

    (*) Makes some /proc changes:

    (*) /proc/devices does not list any blockdevs.

    (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.

    (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.

    (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if
    given command other than Q_SYNC or if a special device is specified.

    (*) In init/do_mounts.c, no reference is made to the blockdev routines if
    CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2.

    (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return
    error ENOSYS by way of cond_syscall if so).

    (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if
    CONFIG_BLOCK is not set, since they can't then happen.

  • 4aff5e233   [PATCH] Split struct request ->flags into two parts ... Browse Code »

    Right now ->flags is a bit of a mess: some are request types, and
    others are just modifiers. Clean this up by splitting it into
    ->cmd_type and ->cmd_flags. This allows introduction of generic
    Linux block message types, useful for sending generic Linux commands
    to block devices.

  • 86e33a296   [SCSI] add shared tag map helpers ... Browse Code »

    This patch adds support for sharing tag maps at the host level
    (i.e. either every queue [LUN] has its own tag map or there's a single
    one for the entire host). This formulation is primarily intended to
    help single issue queue hardware, like the aic7xxx

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
