According to include/uapi/linux/auto_fs.h, include/uapi/linux/auto_fs4.h, and include/linux/auto_dev-ioctl.h, nr part of AUTOFS_IOC_XXX starts off from 0x60 and AUTOFS_DEV_IOCTL_XXX starts off from 0x71 which is 0x60+0x11. >From the way above macros are defined, it seems AUTOFS_DEV_IOCTL_IOC_COUNT should be (0x20-0x11) instead of (0x20-11). (Otherwise it's hard to figure out where 11 comes from) COUNT macros are being used to test distance of an ioctl command in question from the smallest one, so we don't want it to be larger than necessary.
