[lustre-discuss] Setting infinite grace period with soft quotas

[Andreas Dilger]

I do see in the lfs setquota usage message and lfs-setquota.1 man page:

    "The maximum quota grace time is 2^48 - 1 seconds."

That's about 9M years, so it should probably be long enough?  It might
make sense to map "-1" internally to "(1 << 48) - 1" to make this easier.
