Howdy,
Can anybody tell me why the size of ioctl messages is limited
to 256 bytes on mips:
include/asm-mips/ioctl.h:
...
/*
* We to additionally limit parameters to a maximum 255 bytes.
*/
#define _IOC_SLMASK 0xff
...
I would like to see this changed because the PCMCIA software
(cardmgr <-> driver services) needs to pass ioctl messages
around that are a lot bigger than 256 bytes.
Greetz,
Tom

As of today this is only historic garbage, so _IOC_SLMASK can go away.
