These details about other systems were added in 1999,

However, they do clutter the page, so remove them.

ioctl_list.2: BLKRASET/BLKRAGET take unsigned long
...
The BLKRASET/BLKRAGET ioctls() take unsigned long, if I pass int * to
the BLKRAGET ioctl on x86_64 (or on any other arch where sizeof(int) !=
sizeof(long)) the BLKRAGET ioctl will rewrite four bytes on the stack.
If you look at block/ioctl.c in kernel sources you can clearly see that
BLKRAGET ioctl calls put_long().
Compile following reproducer and run it as ./a.out /dev/sda, you can see
that the second member of the array will be zeroed. If you change the
array to have only one member you will see stack smashing trace.
I also wonder if it's OK to pass int value to ioctl() at all, the arg
value seems to be unsigned long in the syscall definition in fs/ioctl.c
and there does not seem to be any glibc magic around the syscall.
