Argg. That's also non-funny:
[hch@sb linux]$ grep __kernel_dev_t; include/asm-*/posix_types.h include/asm-alpha/posix_types.h:typedef unsigned int __kernel_dev_t; include/asm-arm/posix_types.h:typedef unsigned short __kernel_dev_t; include/asm-cris/posix_types.h:typedef unsigned short __kernel_dev_t; include/asm-i386/posix_types.h:typedef unsigned short __kernel_dev_t; include/asm-ia64/posix_types.h:typedef unsigned int __kernel_dev_t; include/asm-m68k/posix_types.h:typedef unsigned short __kernel_dev_t; include/asm-mips64/posix_types.h:typedef unsigned int __kernel_dev_t; include/asm-mips/posix_types.h:typedef unsigned int __kernel_dev_t; include/asm-parisc/posix_types.h:typedef unsigned int __kernel_dev_t; include/asm-ppc/posix_types.h:typedef unsigned int __kernel_dev_t; include/asm-s390/posix_types.h:typedef unsigned short __kernel_dev_t; include/asm-s390x/posix_types.h:typedef unsigned int __kernel_dev_t; include/asm-sh/posix_types.h:typedef unsigned short __kernel_dev_t; include/asm-sparc64/posix_types.h:typedef unsigned int __kernel_dev_t; include/asm-sparc/posix_types.h:typedef unsigned short __kernel_dev_t;
