Linux iscsi driver update 4.0.1.9

Folks,

Thanks to all of you for providing and reviewing patches. Special thanks to Christopher and James Bottomley.
https://sourceforge.net/project/shownotes.php?release_id=268685

This version of the iSCSI driver (4.0.1.9) contains the following changes since 4.0.1.8:

1)The iSCSI driver has undergone architectural changes. The driver now supports one HBA per transport end point( i.e., per iSCSI session).

2)Earlier the iSCSI driver had it's own code to probe LUNs. Now it uses SCSI-ml provided scsi_scan_host() to probe and configure LUNs.

3)Multiple kmaps from rx path have now been removed.

4)The driver used to provide persistant naming of iSCSI devices using 'udev'. The names used to be based on bus id and target id of the session which inturn were kept persistant across boots. The driver no longer supports this. This is to be consistent with the rest of HBA drivers.

5)The code has been cleaned up further. We no longer have mixed case names in the kernel files.

The following items are being worked on/debated:

a)cleanup of threading, signals, interfaces.
removal of dead code
cleaning up of error paths
some cleanup of timer, ipv6,logging

b)Changes so as to be compliant with driver model.

c)Usage of mid layer provided APIs to traverse through device list instead of using session_list link in iscsi_dev_data.

d)Usage of new timeout infrastructure to get rid of iSCSI driver's eh_timeout modifications.

e)Removal of portal-failover feature.

f)Usage of new TCQ APIs(yet to provided in linux 2.6) to get rid of iSCSI driver's mechanism to generate tags.

h)Replacement of ioctls with sysfs interface.

PS The current driver is tested against 2.6.8.1 linux kernel.

Thanks,
Naveen.
