Linus,

For the last several weeks, I've been posting FibreChannel and SCSI 
hotswap driver for the 2.5.44 tree to linux-scsi and linux-kernel.  The 
patch includes complete locking for correct insertion and removal 
without screwing the SCSI subsystem, fibrechannel support for FC targets 
(insertion or removal by wwn), scsi support for scsi targets, and 
complete integration with driverfs.

This patch has been reviewed by Alan Cox, Greg KH, Christoph Hellwig, 
Patrick Mansfield, Rob Landly, Jeff Garzik, Scott Murray, James 
Bottomley, Mike Anderson, Randy Dunlap and Patrick Mochel.  Some of the 
developers have suggested they would integrate it into 2.5.45.  I've 
made changes suggested by the above contributors and feel the patch is 
really as good as its going to get (minus some scsi spin down and cache 
flushing additions I want to make).   These can be made post freeze if I 
get to them.

Please ignore the patch to the qlogic driver, as it is not integrated 
into the kernel and is only in my development tree.
