The patch worked perfectly on our test configuration. After the SCST
target reboot the client initiator picked up on the presence of the
storage and properly discovered it.
Evidently the qla2xxx driver has changed significantly from where
Linus' tree was at when you sent the patch. My local git clone is up
to date with Linus' git tree which has
94ad374a0751f40d25e22e036c37f7263569d24c at its head and the patch
didn't apply.
The kernel I tested against was from my local git clone of Linus' tree
which has 94ad374a0751f40d25e22e036c37f7263569d24c at its head. The
qla2xxx driver has evidently changed significantly since the patch
didn't apply cleanly against this tree. It was trivial, however, to
update the patch.

That would seem to be the case. It doesn't appear 2.6.26 even has the
necessary infra-structure to support the patch.
Any idea on how tough a backport to 2.6.26 or earlier would be?
Running 'head-of-git' from Linus' tree would be somewhat of a stretch
for production applications.... :-)(
Thanks for the timely response. Let me know if we can help out with
any additional testing.
Best wishes for a pleasant weekend.
