I applied the nfs_all patch from
http://www.fys.uio.no/~trondmy/src/2.4.19/ to a linux-2.4.19 kernel, and
ran into trouble compiling.

In particular, the linux-2.4.19-02-fix_kmap2.dif patch defines a
conflicting type for xdr_shift_buf's second argument.  In
linux-2.4.19/include/linux/sunrpc/xdr.h, it is defined to be of type
unsigned int, and in linux-2.4.19/net/sunrpc/xdr.c, it is defined to be
of type size_t.

Size_t is defined to be __kernel_size_t in /usr/include/linux/types.h,
which is defined to be unsigned long in /usr/include/asm/posix_types.h.

On an IA32 architecture, unsigned long and unsigned int are the same, so
this is not a big deal.  However, on an alpha, a long is 64 bits,
whereas an int is only 32 bits.

Should xdr_shift_buf take an int or a long?  Are there any other known
problems for a 64-bit architecture in the nfs_all patches?

Thank you,

dbr
