fid->raw could be 32-bit aligned, couldn't it?
#include <asm/unaligned.h>
u64 ino = get_unaligned((u64 *)fh);
derr(10, "fh_to_parent %llx.%x\n",
(unsigned long long)ino, hash);
(not tested)
I remember somebody saying that u64 should become unsigned long long on
all architectures eventually; is there still such a plan?
