2007-10-12[SCSI] Fix async scanning double-add problemsMatthew Wilcox
Stress-testing and some thought has revealed some places where asynchronous scanning needs some more attention to locking. - Since async_scan is a bit, we need to hold the host_lock while modifying it to prevent races against other CPUs modifying the word that bit is in. This is probably a theoretical race for the moment, but other patches may change that. - The async_scan bit means not only that this host is being scanned asynchronously, but that all the devices attached to this host are not yet added to sysfs. So we must ensure that this bit is always in sync. I've chosen to do this with the scan_mutex since it's already acquired in most of the right places. - If the host changes state to deleted while we're in the middle of a scan, we'll end up with some devices on the host's list which must be deleted. Add a check to scsi_sysfs_add_devices() to ensure the host is still running. - To avoid the async_scan bit being protected by three locks, the async_scan_lock now only protects the scanning_list.

2007-10-12[SCSI] srp_transport: add target driver supportFUJITA Tomonori

2007-10-12[SCSI] tgt: add I_T nexus supportFUJITA Tomonori
tgt uses scsi_host as I_T nexus. This works for ibmvstgt because it creates one scsi_host for one initiator. However, other target drivers don't work like that. This adds I_T nexus support, which enable one scsi_host to handle multiple initiators. New scsi_tgt_it_nexus_create/destroy functions are expected be called transport classes. For example, ibmvstgt creates an initiator remote port, then the srp transport calls tgt_it_nexus_create. tgt doesn't manages I_T nexus, instead it tells tgtd, user-space daemon, to create a new I_T nexus. On the receiving the response from tgtd, tgt calls shost->transportt->it_nexus_response. transports should notify a lld. The srp transport uses it_nexus_response callback in srp_function_template to do that.

2007-08-13[NET]: Share correct feature code between bridging and bondingHerbert Xu
http://bugzilla.kernel.org/show_bug.cgi?id=8797 shows that the bonding driver may produce bogus combinations of the checksum flags and SG/TSO. For example, if you bond devices with NETIF_F_HW_CSUM and NETIF_F_IP_CSUM you'll end up with a bonding device that has neither flag set. If both have TSO then this produces an illegal combination. The bridge device on the other hand has the correct code to deal with this. In fact, the same code can be used for both. So this patch moves that logic into net/core/dev.c and uses it for both bonding and bridging. In the process I've made small adjustments such as only setting GSO_ROBUST if at least one constituent device supports it.
