The scsi/scsi.h header is normally provided by the libc (and was not
exported by the kernel since 2.6.24) and has been until it was
re-exported with 2.6.31. The kernel version is not userspace clean and
does not appear to provide anything useable in userland over the
(e)glibc version.

Export fc_els.h, fc_fs.h, fc_gs.h and fc_ns.h so that they
may be used by applications.
This will be needed for FC Passthrough applications like fcping,
but could be used by other applications.

Attached is the ELS/CT pass-thru patch for the FC Transport. The patch
creates a generic framework that lays on top of bsg and the SGIO v4 ioctl
in order to pass transaction requests to LLDD's.
The interface supports the following operations:
On an fc_host basis:
Request login to the specified N_Port_ID, creating an fc_rport.
Request logout of the specified N_Port_ID, deleting an fc_rport
Send ELS request to specified N_Port_ID w/o requiring a login, and
wait for ELS response.
Send CT request to specified N_Port_ID and wait for CT response.
Login is required, but LLDD is allowed to manage login and decide
whether it stays in place after the request is satisfied.
Vendor-Unique request. Allows a LLDD-specific request to be passed
to the LLDD, and the passing of a response back to the application.
On an fc_rport basis:
Send ELS request to nport and wait for ELS response.
Send CT request to nport and wait for CT response.
The patch also exports several headers from include/scsi such that
they can be available to user-space applications:
include/scsi/scsi.h
include/scsi/scsi_netlink.h
include/scsi/scsi_netlink_fc.h
include/scsi/scsi_bsg_fc.h
