I am implementing an Encrypted File system on Minix3. The 32 byte
key(encrypted ofcourse) is stored in the beginning of each block. This
involves changing a few things...
I added d4_inode in fs/types.h, which is basically d2_inode along with
a char array to store the keys. Due to an increase in inode size, will
there be any changes in the number of zones(direct & indirect)??

fs/const.h contains number of zones for V1 and V2 systems. What were
the reason behind the allocation of those particular values??
