Change the second and third args to struct vfsops' (*vfs_mount)() to
...
'const char *', and 'void *', respectively. The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions. The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

Make the struct lfs 512 bytes long on 32bit machines whose compiler doesn't
...
align 32bit integers. Use explicit sized typing at some other places.
XXX This still won't fix lfs for 64bit machines, as we have some
assumptions about sizeof(pointer)=sizeof(u_int32_t) in here, and (if I
looked right) a misaligned u_int64_t. The right fix (to cite cgd) will
be to seperate on-disk-representation from in-core, but I don't have
the time (at the moment) to do this.

cast int64_t-sized types to "long long" before printing them with %qd.
...
gcc thinks that the 'q' modifier describes a "long long", and so -Wformat
whines when printing with 'q' on the alpha, since int64_t-sized types are
done with variations on "long" rather than "long long".

Fix vop_link, vop_symlink, and vop_remove semantics in several ways:
...
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
cleanup.
* Require the file system to decide whether or not linking and unlinking of
directories is allowed, and disable it for all current file systems.
