    Pull SCSI scatter-gather list updates from James Bottomley:
    "This topic branch covers a fundamental change in how our sg lists are
    allocated to make mq more efficient by reducing the size of the
    preallocated sg list.

    This necessitates a large number of driver changes because the
    previous guarantee that if a driver specified SG_ALL as the size of
    its scatter list, it would get a non-chained list and didn't need to
    bother with scatterlist iterators is now broken and every driver
    *must* use scatterlist iterators.

    This was broken out as a separate topic because we need to convert all
    the drivers before pulling the trigger and unconverted drivers kept
    being found, necessitating a rebase"

  • c3c0fd9b1   scsi: wd33c93: use sg helper to iterate over scatterlist ... Browse Code »

    Unlike the legacy I/O path, scsi-mq preallocates a large array to hold
    the scatterlist for each request. This static allocation can consume
    substantial amounts of memory on modern controllers which support a
    large number of concurrently outstanding requests.

    To facilitate a switch to a smaller static allocation combined with a
    dynamic allocation for requests that need it, we need to make sure all
    SCSI drivers handle chained scatterlists correctly.

    Convert remaining drivers that directly dereference the scatterlist
    array to using the iterator functions.

  • f281233d3   SCSI host lock push-down ... Browse Code »

    Move the mid-layer's ->queuecommand() invocation from being locked
    with the host lock to being unlocked to facilitate speeding up the
    critical path for drivers who don't need this lock taken anyway.

    The patch below presents a simple SCSI host lock push-down as an
    equivalent transformation. No locking or other behavior should change
    with this patch. All existing bugs and locking orders are preserved.

    Additionally, add one parameter to queuecommand,
    struct Scsi_Host *
    and remove one parameter from queuecommand,
    void (*done)(struct scsi_cmnd *)

    Scsi_Host* is a convenient pointer that most host drivers need anyway,
    and 'done' is redundant to struct scsi_cmnd->scsi_done.

    Minimal code disturbance was attempted with this change. Most drivers
    needed only two one-line modifications for their host lock push-down.

  • a5d8421b2   [SCSI] wd33c93: Fast SCSI with WD33C93B ... Browse Code »

    Attached are patches, which help to utilize more of the WD33C93B SCSI
    controller's capabilities.

    1) Added/changed all the necessary code to enable Burst Mode DMA. Only
    Single Byte DMA was used before.

    2) Added/changed all the necessary code to enable Fast-10 SCSI transfers.

    3) The original driver inadvertently used a transfer period of 1000-800ns
    (the lowest possible transfer rate) for asynchronous data transfers,
    instead of the (configurable) default period intended for this purpose,
    if the target responded to a SDTR not with a Reject-message, but with
    a zero-SDTR. This issue was fixed.
    Moreover, in case of a Reject the driver used the default-period's
    initialization-value instead of its (maybe smaller) current value. The
    missing assignment was added.

    4) The driver's commandline- and proc-file-interface was augmented to
    handle the new options properly.

    The WD33C93 manual, found at
    http://www.datasheet.in/datasheet-html/W/D/3/WD33C93B_WesternDigital.pdf.html,
    was very helpful.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    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).

    This patch removes almost all inclusions of linux/version.h. The 3
    #defines are unused in most of the touched files.

    A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
    unfortunatly in linux/version.h.

    There are also lots of #ifdef for long obsolete kernels, this was not
    touched. In a few places, the linux/version.h include was move to where
    the LINUX_VERSION_CODE was used.

    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!
