Description

Design and implement a mechanism that, given a CInode, it will go check the actual disk state of that inode for consistency with the CInode. Initially we just need to verify the parent backpointers, and for directories that the rstats match.
Design it considering the later addition of more extensive checks, such as verifying actual file sizes.
