Since active_mask is first assigned in an "else" block, the compiler throws a warning saying that the active_mask variable may be used uninitialized in a print statement later. Initialize active_mask to 0 in the declaration to stop the warning. Signed-off-by:

Corrects the return value for the cases where read/write edc fails; this prevents sysfs from retrying the operation until forever. Corrects the printk width specifier for the first byte of buf. Signed-off-by:

The Marvell Universal Message Interface (UMI) defines a messaging interface between host and Marvell products (Plato, for example). It considers situations of limited system resource and optimized system performance. UMI driver translates host request to message and sends message to FW via UMI, FW receives message and processes it, then sends response to UMI driver. FW generates an interrupt when it needs to send information or response to UMI driver Signed-off-by:

Added new sysfs attr 'host_reset' in scsi_sysfs.c to perform adapter or firmware reset as suggested by Mike Christie here: http://marc.info/?l=linux-scsi&m=127359347111167&w=2 user/application can write "adapter" or "firmware" on this attr and it will call newly added function hook in scsi_host_template to call LDD adapter or firmware reset implementation.

Some CD-ROMs fail to report a media change correctly. The specific one for this patch simply fails to respond to commands, then gives a UNIT ATTENTION after being reset which returns ASC/ASCQ 28/00. This is out of spec behaviour, but add a check in the eat CC/UA on reset path to catch this case so the CD-ROM will function somewhat properly.

1. Remove device database entry (ddb) state. 2. Remove device database (DDB) list building. With open-iscsi integration the logins to the target devices are handled by the user space. So the information of target is now maintained in the iscsi_session object. This is handled at libiscsi level so there is no need to maintain a list of DDBs in the qla4xxx LLD. 3. qla4xxx: Remove add_device_dynamically. Since autologin in FW is disabled with open-iscsi integration, driver will never get an AEN for which driver has not requested a DDB index. So remove the add_device_dynamically function. 4. Remove qla4xxx_tgt_dscvr Since firmware autologin is disabled this function will not work. Now user has the ability to do the target discovery and login to each target individually. Firwmare will not do the login on its own. 5. Remove relogin related code All relogin is handled by userspace now. qla4xxx just need to notify userspace of a connection failure, this triggers the relogin. 6. Remove add_session and alloc_session Now qla4xxx uses iscsi_session_setup that would do the necessary allocations for session and ddb_entry.

Add scsi_transport_iscsi hooks in qla4xxx to support iSCSI session management using iscsiadm. This patch is based on discussion here http://groups.google.com/group/open-iscsi/browse_thread/thread/e89fd888baf656a0# Now users can use iscsiadm to do target discovery and do login/logout to individual targets using the qla4xxx iSCSI class interface. This patch leaves some dead code, but to make it easier to review we are leaving and in the next patch we will remove that old code. V2 - NOTE: Added code to avoid waiting for AEN during login/logout in the driver, instead added a kernel to user event to notify iscsid about login status. Because of this iscsid will not get blocked. Signed-off-by:

[SCSI] scsi_transport_iscsi: Add conn login, kernel to user, event to support offload session login. Offload drivers like qla4xxx will offload the sending of the login/logout pdus still, so this patch adds iscsi_conn_login_event which is used by these types of drivers to notify userspace that the connection has changed state. It also adds a iscsi_is_session_online helper so the lld can query the sessions state field. Signed-off-by:
