No problem. You added a testcase, it failed. So easy to detect :)

Thanks. I added one small workaround for kernel < 2.6.32 (which isn't
actually released yet) which don't have IRQF_ONESHOT. With that
everything passes also on my systems.

Cheers,

Mark

Subject: [PATCH] Define IRQF_ONESHOT for older kernels.

IRQF_ONESHOT was only introduced in 2.6.32. It doesn't hurt defining it
if it isn't already there. It will just never show up on older kernels.

* tapset/aux_syscalls.stp: Define IRQF_ONESHOT if not already defined.
