mips kernel 2.6.16rc1 + IET 0.4.13 - /dev/ietctl - ioctl unknown command

[Frederic Temporelli <frederic.temporelli@tele2.fr>]

Hello,

I would like to report an ioctl issue using IET 0.4.13 (iSCSI target) 
and kernel 2.6.16-rc1, running on mips / SGI O2

The driver seems to load nicely, but there was no way to do ioctl on the 
userspace device /dev/ietctl.
I got such messages in syslog:
Mar  4 16:47:16 o2 kernel: [4303606.514000] ioctl32(ietd:3448): Unknown 
cmd fd(4) cmd(81046900){01} arg(7f942ab0) on /dev/ietctl

=> I've been able to resolve the issue by adding a by-pass (goto 
do_ioctl) in kernel compat_sys_ioctl function (fs/compat.c)  and all is 
working fine now.

I don't know if such issue is related to mips only or is due to changes 
2.6.16 kernel
I've also did some tries on x86 with linux 2.6.15.5, all was working 
fine without needing to change anything in the kernel.

Did somebody report such issue with IET and recent kernel ?
May some people from linux-mips tell if such issue is mips specific ?

Best regards.
