In structure prison it is added structures containing disk quotas and

At start Jail, we calculate the size root path and number of files in

In functions of allocation of disk blocks and inode, we check quotas and
we increase current use.
UFS cannot determine whether the new allocation goes under the jail
root or not.
Yes. But jail cannot allocate block and inode above root path. In
allocation functions, whether for example ffs_alloc we have access to
ucred process and we can check up there is a process in jail.
Yes, you can check this for jailed process. Think about non-jailed processes
that can do allocation below the jail root.
Processes out of jail are not considered.
I do not understand, these processes have what relation to disk to
quotas for jail. Please explain more in detail
