[PATCH] statfs64/fstatfs64 compat syscall and header fix

To: linux-mips@linux-mips.org
Subject: [PATCH] statfs64/fstatfs64 compat syscall and header fix
From: "Christopher G. Stach II" <cgs@ldsys.net>

    This patch fixes the n32 and o32 syscall tables for compat statfs64
and fstatfs64.  This indirectly fixes statvfs in glibc, etc.

    The statfs.h reorganization (to align it with all of the other
arches and include/linux/statfs.h) isn't as important as the structure
size, which makes the syscalls bomb immediately.

    Also, for anyone interested, the accompanying glibc patch to update
for the updated structure order and size, as well as fix some other
problems for fstatfs64/statfs64, is at:
