Whoa. That's old... :-/

Currently, kconfig uses (CIRCLEQ or TAILQ)

Sorry, I did not see you had posted a patch.

Basically, I don't care what solution we choose. Using TAILQ looks like
being not the solution. So, here are the known options:
1- Michal pointed to tools/firewire/list.h, but those are different from
the CIRCLEQ/TAILQ, and switching is not easy (at least for me after a
quick glance);

1b- note also that drivers/scsi/aic7xxx/queue.h has all of both the CIRCLEQ
and TAILQ macros we're interested in, too, and it looks like it can be
used out of the kernel (eg. for userland);

2- carry the parts of CIRCLEQ (or TAILQ) that we need, and use them if
the system's sys/queue.h does not provide them, as Tetsuo proposed;

3- carry the parts of CIRCLEQ (or TAILQ) that we need, and do not rely
on the system's sys/queue.h to provide them at all.


Michal, what do you think would be the best route to go, to:
1- get a fix in 3.7 ?
2- if the fix for 3.7 is just a workaround, a proper fix for 3.8 ?

Regards,
Yann E. MORIN.
