unsigned short is too small for sizeof(struct scatterlist) * min(q->max_hw_segments, q->max_phys_segments). This fixes memory leak with 4096 segments since 16 (likely sg size with x86) * 4096 sets sglist_len to zero. This might not happen without sg chaining support. Signed-off-by:

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.

This adds minimum target driver support: - srp_rport_{add,del} calls scsi_tgt_it_nexus_{create,destroy} for target drivers. - add a callback to notify target drivers of the nexus operation results to srp_function_template. Signed-off-by: -

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. Signed-off-by:

This adds a 'roles' attribute to rport like transport_fc. The role can be initiator or target. That is, the initiator driver creates target remote ports and the target driver creates initiator remote ports. Signed-off-by:

Build fixes for isp1301_omap driver. I think an earlier version of this must have gotten lost somewhere, or maybe it only went into the Linux-OMAP tree. Also, some whitespace fixes to bring this more into sync with the version of this found in the Linux-OMAP tree. (That version has updates for the OTG controller on the OMAP 1710 which break that functionality on OMAP 161x boards like the H2, so merging all of it is not currently an option.) Signed-off-by:

Due to a mix up between the jdata attribute and inherit jdata attribute it has not been possible to set the inherit jdata attribute on directories. This is now fixed and the ioctl will report the inherit jdata attribute for directories rather than the jdata attribute as it did previously. This stems from our need to have the one bit in the ioctl attr flags mean two different things according to whether the underlying inode is a directory or not. Signed-off-by: -
