We need to lookup the master statfs inode and the local statfs inodes earlier in the mount process (in init_journal) so journal recovery can use them when it attempts to recover the statfs info. We lookup all the local statfs inodes and store them in a linked list to allow a node to recover statfs info for other nodes in the cluster.
