      [PATCH] Lastminute IEEE-1394 fixes · 9b67c27b
      Ben Collins authored
      I've got a lot more changes than what's included here.  I've put this
      down to the bear minimum to get things working sanely.
      
      Mainly, I just want to get all the people hit by this a chance to use
      2.6.0 without having to get our tree. Changes itemized:
      
       - Fix deadlock possibility in csr.c:read_maps()
       - Fix kmalloc to use ATOMIC in highlevel.c.
       - s/in_interrupt/irqs_disabled/ in ieee1394_transactions.c to fix
         warnings when transactions occured.
       - Introduce a release callback for the host driver and use it correctly.
       - Reorganize the nodemgr probe so we do an initial scan to discover
         devices, check IRM/CycleMaster, then do a final full probe when things
         are kosher. Fixes a problem where device registration and hotplug
         would cause some serious problems when a bus reset was forced in the
         middle of the probe.

      Updated state model for SCSI devices · 9b22a8fb
      James Bottomley authored
      I've been looking at enforcing lifetime phases for SCSI devices
      (primarily to try to get the mid layer to offload as much of the device
      creation and hotplug pieces as it can).
      
      I've hijacked the sdev_state field of the struct scsi_device (formerly
      this was a bitmap, now it becomes an enumerated state).
      
      I've also begun adding references sdev_gendev into the code to pin the
      scsi_device---initially in the queue function, but possibly this should
      also be done in the scsi_command_get/put, the idea being to prevent
      scsi_device freeing while there's still device activity.
      
      The object phases I identified are:
      
      1. SDEV_CREATED - we've just allocated the device.  It may respond to
      internally generated commands, but not to user ones (the user should
      actually have no way to access a device in this state, but just in
      case).
      
      2. SDEV_RUNNING - the device is fully operational
      
      3. SDEV_CANCEL - The device is cleanly shutting down.  It may respond to
      internally generated commands (for cancellation/recovery) only; all user
      commands are errored unless they have already been queued (QUEUE_FULL
      handling and the like).
      
      4. SDEV_DEL - The device is gone. *all* commands are errored out.
      
      Ordinarily, the device should move through all four phases from creation
      to destruction, but moving SDEV_RUNNING->SDEV_DEL because of surprise
      ejection should work.
      
      It's starting to look like the online flag should be absorbed into this
      (offlined devices move essentially to SDEV_CANCEL and could be
      reactivated by moving to SDEV_RUNNING).
      
      I haven't altered the similar bitmap model that scsi_host has, although
      this too should probably move to an enumerated state model.
      
      I've tested this by physically yanking a module out from underneath a
      running filesystem with no ill effects (other than a slew of I/O
      errors).
      
      The obvious problem is that this kills possible user error handling, but
      we don't do any of that yet.

      [PATCH] scsi device ref count (update) · e4df9910
      Mike Anderson authored
      This patch is against scsi-bugfixes-2.6. I updated it based on comments
      received. It breaks up the reference count initialization for scsi_device
      and restores calling slave_destroy for all scsi_devices configured or
      not. I ran a small regression using the scsi_debug, aic7xxx, and qla2xxx
      driver. I also had a debug patch for more verbose kobject cleanup and
      patch for a badness check on atomic_dec going negative (previously
      provided by Linus).
      
      The object cleanup appears to being functioning correctly. I only saw
      previously reported badness output:
      	- Synchronizing SCSI cache fails on cleanup.
      	- scsi_debug.c missing release (I believe Doug posted a patch)
      	- aic7xxx warnings on rmmod due to ahc_platform_free calling
      	  scsi_remove_host with ahc_list_lock held.
      
      
      This patch splits the scsi device struct device register into init and
      add. It also addresses memory leak issues of not calling slave_destroy
      on scsi_devices that are not configured in.
      
      Details:
      * Make scsi_device_dev_release extern for scsi_scan to use in
      alloc_sdev.
      * Move scsi_free_sdev code to scsi_device_dev_release. Have
      previous callers of scsi_free_sdev call slave_destroy plus put_device.
      * Changed name of scsi_device_register to scsi_sysfs_add_sdev to
      match host call and align with split struct device init.
      * Move sdev_gendev device and class init to scsi_alloc_sdev.

      [PATCH] More SiS interrupt routing · f6967f9a
      Davide Libenzi authored
      It turns out that the SiS irq routing logic doesn't go by chipset
      after all - it's just that some pirq entries are "legacy" numbers,
      while others are raw offsets into PCI config space (and the legacy
      numbers are more commonly used with the older chipsets, which
      explains the correlations).
      
      This simplifies the router code substantially.
