Hi!
I'm playing with uinput on zaurus (spitz) I've a pxa-2.6 kernel flashed in the
uinput is loaded as module. Right after my program called:

ioctl(fd, UI_DEV_CREATE);

I've got:

WARNING: at mm/page_alloc.c:2012 __alloc_pages_nodemask+0148/0x5a8()

and the ioctl() has failed.

Anybody has an idea what went wrong?

You do not have enough memory?

Maybe if you could post your program we could see what exactly went
wrong...

Thanks.

Gone trought my code once again and found small typo in sizeof() in
uinput_user_dev initialization.

Sorry for the noise.
