In netuse.lists.linux-kernel you write: >Size of individual files themselves is only one dimension of real >large file system support.
Yep, but 64 bit inode number support needs adequate concepts to manage this number of files.
Can you imagine the ext2 data structures with a 64 bit number of files? How long would it take to find a free inode with a linear search in a 64 bit bitmap? How much RAM do you need to hold that many block group descriptors resident?
