quota2 qv_grace

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

I'm confused how the file-system default grace period is supposed to get 
copied to the per-user grace period quota2 supports. It appears that this 
happens as soon as something gets allocated for the user (i.e., just by 
system calls, not by any userland program like edquota). However, I find 
nothing in sys/ufs/ufs/ufs_quota2.c that looks like it does that. What am 
I overlooking?

I remember I wrote the patch that causes qv_timelimit to get set to 
<current time> + qv_grace, but not how the latter gets set.
