Do not automatically "select" SCSI_DH for dm-multipath. If SCSI_DH doesn't exist,just do not allow hardware handlers to be used. Handle SCSI_DH being a module also. Make sure it doesn't allow DM_MULTIPATH to be compiled in when SCSI_DH is a module. [jejb: added comment for Kconfig syntax] Signed-off-by:

The sym53c8xx driver, for some reason, seems to mostly re-implement linux/list.h with added bogosity. The main one is it's implementation of sym_que_entry which spits warnings with recent gcc's on some 64 bits architectures. Signed-off-by:

scsi_lib.c:scsi_host_queue_ready() plugs the device with incorrect locking. It should actually have the queue lock held, but it's holding the host lock. Fix this by eliminating the call. The host ready has no need to plug the queue because if it returns 0 in scsi_request_function control transfers to not_ready which acquires the queue lock and plugs the device if its at zero depth.

This patch adds a new device driver to support the Virtual Fibre Channel interface on IBM Power based servers. The Virtual I/O Server on IBM Power servers utilizes N-Port ID Virtualization to export a Virtual Fibre Channel adapter to the client. This driver is the client device driver. Signed-off-by:

Update iscsi class version number. Signed-off-by:

Mike Christie authored
This patch fixes two bugs that are related. 1. Old tools did not set can_queue/cmds_max. This patch modifies libiscsi so that when we add the host we catch this and set it to the default. 2. iscsi_tcp thought that the scsi command that was passed to the eh functions needed a iscsi_cmd_task allocated for it. It only needed a mgmt task, and now it does not matter since it all comes from the same pool and libiscsi handles this for the drivers. ib_iser had copied iscsi_tcp's code and set can_queue to its max - 1 to handle this. So this patch removes the max -1, and just sets it to the max. Signed-off-by:

The sysfs attribute /sys/class/fc_host/hostX/port_state was not set by zfcp so far. Now, the appropriate members of the fc_function_template struct are set during its initialziation. The first is a boolean to show the port state. The second is a function pointer to the function zfcp_get_host_port_state, which reads the port state from our adapter status bits and calls fc_host_port_state with the approriate port state afterwards.
