James,
I don't see this patch in 2.6.33-rc5? Any specific reason?
Thanks,

James,
I don't see this patch from Fujita included in your scsi-rc-
fixes-2.6.git. This is required to run 32 bit BSG application on 64
bit system. Can u please include this.
Thanks,
Giridhar Malavali

bsg's SG_IO doesn't work on 32-bit userspace and 64-bit kernelspace.
The problem is that both sg and bsg drivers use SG_IO
ioctl. sg_ioctl_trans() does 32/64-bit conversion even against bsg
header. It messes up bsg header. bsg driver gets garbage.
This patch fixes sg_ioctl_trans to handle only sg header (struct
sg_io_hdr).
