Subject: [Q] MEMGETREGIONxxx ioctls
Here are a few questions related to the MEMGETREGIONxxx ioctls.
I'd simply submit a patch, but I am not sure about the reasoning
and I'm not near a build system for verification:
1) Why is MEMGETREGIONCOUNT declared with _IOW
instead of _IOR in mtd.h? It seems to be a
read from kernelspace, rather than a write to
kernelspace in mtdchar.c.
2) Why is MEMGETREGIONINFO declared likewise with _IOW
instead of _IOWR? The ioctl in mtdchar.c reads the
regionindex member and then populates the rest of the
3) Do we need the declaration of
"struct mtd_erase_region_info *kr"
inside the MEMGETREGIONINFO ioctl handler? It is
initialized but never used, so I doubt it is necessary.
