Replace the mac_esp driver with a new one based on the esp_scsi core. For esp_scsi: add support for sync transfers for the PIO mode, add a new esp_driver_ops method to get the maximum dma transfer size (like the old NCR53C9x driver), and some cleanups. Signed-off-by:

The new FCP adapter statistics provide a variety of information about the virtual adapter (subchannel). In order to collect this information the zfcp driver is extended to query this information. The information provided by the new FCP adapter statistics can be fetched by reading from the following files in the sysfs filesystem /sys/class/scsi_host/host<n>/seconds_active /sys/class/scsi_host/host<n>/requests /sys/class/scsi_host/host<n>/megabytes /sys/class/scsi_host/host<n>/utilization These are the statistics on a virtual adapter (subchannel) level. The information provided is raw and not modified or interpreted by any means. No interpretation or modification of the values is done by the zfcp driver. Signed-off-by:

Way back when, when the fc_user_scan routine was created, it kept some of its original logic that walked the rport list and kicked off a scan. Unfortunately, it didn't keep any of the locking around the rport list, nor did it consider the synchronous nature of the scan invoked. The result, there are some scan requests where the rport list changes, thus a subsequent scan is called on a bogus rport structure and the system NMI's. Signed-off-by:

We're getting a WARN_ON from SLUB indicating that we're trying to free caches with in-use objects. The root cause is a new dependency in the command/sense free on unchecked_isa_dma. The WARN_ON is caused by drivers which change this in their setup after the command/sense cache is allocated. The fix is to move the allocation of this cache into scsi_add_host() so things like gdth have an opportunity to modify it between alloc and add (but *not* after). The true fix would be to move unchecked_isa_dma into the template and out of the host, so it because a truly read only variable. Signed-off-by:

The driver stores the PCI resource address into 'u_long' variable before calling ioremap_nocache() on it. This warrants kernel oops when the registers are accessed on PPC 44x platforms which (being 32-bit) have PCI memory space mapped beyond 4 GB. The arch/ppc/ kernel has a fixup in ioremap() that helps create an illusion that the PCI memory resources are mapped below 4 GB, but arch/powerpc/ code got rid of this trick, having instead CONFIG_RESOURCES_64BIT enabled.

scsi_transport_sas calls blk_cleanup_queue too early for bsg queues. If a user holds a sas_host, end_device, or expander device open, remove the device, then send a request to it, we get a kernel crash. We need to call blk_cleanup_queue in the release callback as we do with scsi devices. This patch moves blk_cleanup_queue to sas_expander_release and sas_end_device_release from sas_bsg_remove. sas_host can't use the release callback in struct device so use bsg's release callback.

This patch adds release callback support, which is called when a bsg device goes away. bsg_register_queue() takes a pointer to a callback function. This feature is useful for stuff like sas_host that can't use the release callback in struct device. If a caller doesn't need bsg's release callback, it can call bsg_register_queue() with NULL pointer (e.g. scsi devices can use release callback in struct device so they don't need bsg's callback). With this patch, bsg uses kref for refcounts on bsg devices instead of get/put_device in fops->open/release. bsg calls put_device and the caller's release callback (if it was registered) in kref_put's release.

The current target allocation code registeres each possible target with sysfs; it will be deleted again if no useable LUN on this target was found. This results in a string of 'target add/target remove' uevents. Based on a patch by Hannes Reinecke <hare@suse.de> this patch reworks the target allocation code so that only uevents for existing targets are sent. The sysfs registration is split off from the existing scsi_target_alloc() into a in a new scsi_add_target() function, which should be called whenever an existing target is found. Only then a uevent is sent, so we'll be generating events for existing targets only. Signed-off-by:

We have a problem in scsi_transport_spi in that we need to customise not only the visibility of the attributes, but also their mode.

Before IBA7220 support was added, the ipath driver didn't support any hardware unless PCI_MSI and/or HT_IRQ was enabled. However, the IBA7220 can generate INTx interrupts, so it makes sense to allow the driver to be build even if PCI_MSI=n and HT_IRQ=n. Signed-off-by:
