From: Bastian Blank <[email protected]> Both the FIBMAP and FIGETBSZ ioctl get "int *" (pointer to 32bit integer) as argument, not "long *" as specified in qemu. Using the correct type makes the emulation work in cross endian context.
Both ioctl does not seem to be documented. However the kernel implementation has always used "int *".
