Attached is an update of the Advanced TCA disk hotswap driver to provide 
disk hotswap
support for the Linux Kernel 2.5.44.  Hotswap targets include both SCSI 
and FibreChannel.
Note this support is generic in that it will work in a typical PC system 
with SCSI or
FibreChannel disks.

The patch includes support for the QLA adaptor but this adaptor is not 
included in the
standard linux kernel.  If you havn't patched your kernel with this 
driver, just ignore the
patch for the qla adaptor to still gain all functionality except for 
hotswap using
that adaptor for WWN identifiers.

As always, the latest Advanced TCA hotswap patches (including scsi disk 
hotswap) can be found:

Changes from kernel 2.5.44 0.90 to 0.91 release:
-----------------------------------------------------------------
* Dumped custom ramfs and integrated with driverfs under 
bus/scsi/hotswap_commads (suggested by several people)
* changed read_file to _show and write_file to _store while also 
changing symantics
* switched lun/id and lun/wwn ordering to id/lun and wwn/lun (pointed as 
an error by Michael Anderson)
* spinlocks changed to semaphores to fix lock held during sleep in 
function scsi_eh_bus_device_reset (pointed as an error by Patrick Mansfield)

Thanks for looking at the patch...
