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.

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.Signed-off-by: Matthew Wilcox

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: FUJITA Tomonori

Signed-off-by: James Bottomley -
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: FUJITA Tomonori

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: FUJITA Tomonori

This adds srp transport class that works with ib_srp and ibmvscsi.
It creates only /sys/class/{srp_host,srp_remote_ports} and

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: David Brownell

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: Steven Whitehouse
