An inode number describes exactly one file on the file system. The inode number should not change. inode numbers are stored in the on-disk inode.
In that case, how do you make sure that there are no inode-number collisions between different filesystems mounted ? if every filesystem is responsible to allocate and remember its inodes, can't you reach a situation where two filesystems you mount gave the same inode number to different files ? given the inode number in this case, how you can reach the right file ? thanks !!! jakko -- Kernelnewbies: Help each other learn about the Linux kernel.
