  • e18b890bb   [PATCH] slab: remove kmem_cache_t ... Browse Code »

    Replace all uses of kmem_cache_t with struct kmem_cache.

    The patch was generated using the following script:

    #!/bin/sh
    #
    # Replace one string by another in all the kernel sources.
    #

    set -e

    for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do
    quilt add $file
    sed -e "1,\$s/$1/$2/g" $file >/tmp/$$
    mv /tmp/$$ $file
    quilt refresh
    done

    The script was run like this

    sh replace kmem_cache_t "struct kmem_cache"

  • 97f78759e   [SCSI] scsi tgt: scsi target user and kernel communication interface ... Browse Code »

    The user-space daemon and tgt kernel module need bi-directional
    kernel/user high-performance interface, however, mainline provides no
    standard interface like that.

    This patch adds shared memory interface between kernel and user spaces
    like some other drivers do by using own character device. The
    user-space daemon and tgt kernel module creates shared memory via mmap
    and use it like ring buffer. poll (kernel to user) and write (user to
    kernel) system calls are used for notification.

    The core scsi target lib functions.

    TODO:
    - mv md/dm-bio-list.h to linux/bio-list.h so md and us do not have to
    do that weird include.
    - convert scsi_tgt_cmd's work struct to James's execute code. And try
    to kill our scsi_tgt_cmd.
    - add host state checking. We do refcouting so hotplug is partially
    supported, but we need to add state checking to make it easier on
    the LLD.

  • b58d91547   [SCSI] export scsi-ml functions needed by tgt_scsi_lib and its LLDs ... Browse Code »

    This patch contains the needed changes to the scsi-ml for the target
    mode support.

    Note, per the last review we moved almost all the fields we added
    to the scsi_cmnd to our internal data structure which we are going
    to try and kill off when we can replace it with support from other
    parts of the kernel.

    The one field we left on was the offset variable. This is needed to handle
    the case where the target gets request that is so large that it cannot
    execute it in one dma operation. So max_secotors or a segment limit may
    limit the size of the transfer. In this case our tgt core code will
    break up the command into managable transfers and send them to the
    LLD one at a time. The offset is then used to tell the LLD where in
    the command we are at. Is there another field on the scsi_cmd for
    that?

  • 1aa8fab2a   [SCSI] Make scsi_scan_host work for drivers which find their own targets ... Browse Code »

    If a driver can find its own targets, it can now fill in scan_finished and
    (optionally) scan_start in the scsi_host_template. Then, when it calls
    scsi_scan_host(), it will be called back (from a thread if asynchronous
    discovery is enabled), first to start the scan, and then at intervals to
    check if the scan is completed.

    Also make scsi_prep_async_scan and scsi_finish_async_scan static.

    This patch implements a REQ_DEVICE_RESET handler for the aic94xx
    driver. Like the earlier REQ_TASK_ABORT patch, this patch defers the
    device reset to the Scsi_Host's workqueue, which has the added benefit
    of ensuring that the device reset does not happen at the same time
    that the abort tmfs are being processed. After the phy reset, the
    busted drive should go away and be re-detected later, which is indeed
    what I've seen on both a x260 and a x206m.

  • 43a145a34   [SCSI] iscsi class: fix slab corruption during restart ... Browse Code »

    The transport class recv mempools are causing slab corruption.
    We could hack around netlink's lack of mempool support like dm,
    but it is just too ulgy (dm's hack is ugly enough :) when you need
    to support broadcast.

    This patch removes the recv pools. We have not used them even when
    we were allocting 20 MB per session and the system only had 64 MBs.
    And we have no pools on the send side and have been ok there. When
    Peter's work gets merged we can use that since the network guys
    are in favor of that approach and are not going to add mempools
    everywhere.

  • 3e082a910   [SCSI] Add ability to scan scsi busses asynchronously ... Browse Code »

    Since it often takes around 20-30 seconds to scan a scsi bus, it's
    highly advantageous to do this in parallel with other things. The bulk
    of this patch is ensuring that devices don't change numbering, and that
    all devices are discovered prior to trying to start init. For those
    who build SCSI as modules, there's a new scsi_wait_scan module that will
    ensure all bus scans are finished.

    This patch only handles drivers which call scsi_scan_host. Fibre Channel,
    SAS, SATA, USB and Firewire all need additional work.

  • 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.

  • 6460e75a1   [SCSI] sg: fixes for large page_size ... Browse Code »

    This sg driver patch addresses the problem with larger
    page sizes reported by Brian King in this post:
    http://marc.theaimsgroup.com/?l=linux-scsi&m=115867718623631&w=2
    Some other related matters are also addressed. Some of these
    prevent oopses when the SG_SCATTER_SZ or scatter_elem_sz are
    set to inappropriate values.

    The scatter_elem_sz has been tested up to 4 MB which should
    make the largest data transfer with one SCSI command, 32 MB
    less one block, achievable with a relatively small number
    of elements in the scatter gather list.

    ChangeLog:
    - add scatter_elem_sz boot time parameter and sysfs module
    parameter that is initialized to SG_SCATTER_SZ
    - the driver will then adjust scatter_elem_sz to be the
    max(given(scatter_elem_sz), PAGE_SIZE)
    It will also round it up, if necessary, to be a power
    of two
    - clean up sg.h header, correct bad urls and some statements
    that are no longer valid
    - make the def_reserved_size sysfs module attribute writable

  • 0f29b966d   [SCSI] FC transport: Add dev_loss_tmo callbacks, and new fast_io_fail_tmo w/ callback ... Browse Code »

    This patch adds the following functionality to the FC transport:

    - dev_loss_tmo LLDD callback :
    Called to essentially confirm the deletion of an rport. Thus, it is
    called whenever the dev_loss_tmo fires, or when the rport is deleted
    due to other circumstances (module unload, etc). It is expected that
    the callback will initiate the termination of any outstanding i/o on
    the rport.

    - fast_io_fail_tmo and LLD callback:
    There are some cases where it may take a long while to truly determine
    device loss, but the system is in a multipathing configuration that if
    the i/o was failed quickly (faster than dev_loss_tmo), it could be
    redirected to a different path and completed sooner.

    Many thanks to Mike Reed who cleaned up the initial RFC in support
    of this post.
