When James Smart fixed the issue of the userspace scan atributes crashing the system with the FC transport class he added a patch to let the transport class check if the parent is valid for a given transport class. When adding support for the integrated raid of fusion sas devices we ran into a problem with that, as it didn't allow adding virtual raid volumes without the transport class knowing about it. So this patch adds a user_scan attribute instead, that takes over from scsi_scan_host_selected if the transport class sets it and thus lets the transport class control the user-initiated scanning. As this plugs the hole about user-initiated scanning the target_parent hook goes away and we rely on callers of the scanning routines to do something sensible. For SAS this meant I had to switch from a spinlock to a mutex to synchronize the topology linked lists, in FC they were completely unsynchronized which seems wrong.

Adds hotplug support for SAS end devices. Unfortunately the fusion firmware doesn't generate similar events for expanders addition/removal so we can't support them yet. Eric has an idea about a clever scheme to find out about expander changes so that'll be added later on.

The problem in dpt_i2o could be the pci config space accesses it triggers as it loads, dangerous to do if there is any I/O activity going on in the other driver (probable if a boot driver I guess). I approve this patch to dpt_i2o.c, and am applying it to the Adaptec branch of the driver. Thanks for the investigation Ryoji. --- In linux 2.6.15, data transfer does hang when both dpt_i2o and i2o_block drivers are loaded. It seems that location of pci_request_regions() are wrong. I moved it just behind pci_enable_device() like other drivers, and it becomes fine. Signed-off-by: Ryoji Kamei <kamei@miraclelinux.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Added host stats, removed superfluous get_starget_ functions, removed some attributes from zfcp specific sysfs tree (e.g. scsi_host_no, scsi_lun, wwnn and d_id). Host stats are given for the physical adapter port not for the virtual adapter. Reset stats is implemented in the device driver.

Add fc_host attribute permanent_port_name which is used to show the port name of the primary port - the port that initially logged into the fabric. For a virtual port (registered via the primary port with FDISC command) it is useful to know not only its (virtual) port name but also the permanent port name.

LLDDs should never see REQ_BLOCK_PC requests, we can handle them just fine in the core code. There is a small behaviour change in that some check in sr's rw_intr are bypassed, but I consider the old behaviour a bug. Mike found this cleanup opportunity and provdided early patches, so all the credit goes to him, even if I redid the patches from scratch beause that was easier than forward-porting the old patches.

We need to iterate over all children when removing and expander, else stale objects will be around after host removal. This fixes the oops Eric Moore saw when removing and reloading mptsas. Also don't try the scsi_remove_target call unless operating on an end device. The current unconditional call is harmless but confusing.

While trying to get SUSE's SLES9 working on system with more than 4GB we've noticed that SCSI layer happilly passes addresses over 4GB to the buslogic driver, which is quite a big problem as buslogic can generate only 32bit busmastering cycles. Fortunately in the current kernels this problem does not exist anymore as SCSI layer now assumes 4GB capable device by default, but it is still good idea to pass correct device structure to the SCSI layer. If nothing else, /sys/block/sda/device now points to /sys/devices/pci0000:00/0000:00:10.0/host0/... instead of /sys/devices/platform/host0/... like it did in the past. Change does nothing for ISA based BusLogic adapters, they'll still end under platform (and they are probably broken for long time as I do not see anything forcing ISA 16MB limit for them).

o This fix was posted for i386 long back. Posting it for x86_64. http://marc.theaimsgroup.com/?l=linux-kernel&m=110380103229830&w=2 o This patch fixes the problem of secondary cpus boot up. This situation is faced when kernel is built for default locations like 16MB and onwards. In this configuration, only primary cpu (BP) comes and secondary cpus don't boot. o Problem occurs because in trampoline code, lgdt is not able to load the GDT as it happens to be situated beyond 16MB. This is due to the fact that cpu is still in real mode and default operand size is 16bit. o This patch uses lgdtl instead of lgdt to force operand size to 32 instead of 16.
