  • db5ed4dfd   scsi: drop reason argument from ->change_queue_depth ... Browse Code »

    Drop the now unused reason argument from the ->change_queue_depth method.
    Also add a return value to scsi_adjust_queue_depth, and rename it to
    scsi_change_queue_depth now that it can be used as the default
    ->change_queue_depth implementation.

  • c8b09f6fb   scsi: don't set tagging state from scsi_adjust_queue_depth ... Browse Code »

    Remove the tagged argument from scsi_adjust_queue_depth, and just let it
    handle the queue depth. For most drivers those two are fairly separate,
    given that most modern drivers don't care about the SCSI "tagged" status
    of a command at all, and many old drivers allow queuing of multiple
    untagged commands in the driver.

    Instead we start out with the ->simple_tags flag set before calling
    ->slave_configure, which is how all drivers actually looking at
    ->simple_tags except for one worke anyway. The one other case looks
    broken, but I've kept the behavior as-is for now.

    Except for that we only change ->simple_tags from the ->change_queue_type,
    and when rejecting a tag message in a single driver, so keeping this
    churn out of scsi_adjust_queue_depth is a clear win.

    Now that the usage of scsi_adjust_queue_depth is more obvious we can
    also remove all the trivial instances in ->slave_alloc or ->slave_configure
    that just set it to the cmd_per_lun default.

  • 2ecb204d0   scsi: always assign block layer tags if enabled ... Browse Code »

    Allow a driver to ask for block layer tags by setting .use_blk_tags in the
    host template, in which case it will always see a valid value in
    request->tag, similar to the behavior when using blk-mq. This means even
    SCSI "untagged" commands will now have a tag, which is especially useful
    when using a host-wide tag map.

  • 506686333   scsi: remove abuses of scsi_populate_tag ... Browse Code »

    Unless we want to build a SPI tag message we should just check SCMD_TAGGED
    instead of reverse engineering a tag type through the use of
    scsi_populate_tag_msg.

    Also rename the function to spi_populate_tag_msg, make it behave like the
    other spi message helpers, and move it to the spi transport class.

  • 125c99bc8   scsi: add new scsi-command flag for tagged commands ... Browse Code »

    Currently scsi piggy backs on the block layer to define the concept
    of a tagged command. But we want to be able to have block-level host-wide
    tags assigned even for untagged commands like the initial INQUIRY, so add
    a new SCSI-level flag for commands that are tagged at the scsi level, so
    that even commands without that set can have tags assigned to them. Note
    that this alredy is the case for the blk-mq code path, and this just lets
    the old path catch up with it.

    We also set this flag based upon sdev->simple_tags instead of the block
    queue flag, so that it is entirely independent of the block layer tagging,
    and thus always correct even if a driver doesn't use block level tagging
    yet.

    Also remove the old blk_rq_tagged; it was only used by SCSI drivers, and
    removing it forces them to look for the proper replacement.

  • 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.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.
