My first thought is to avoid the issue altogether by using a file system that doesn't statically allocate inodes (e.g. XFS or reiserfs, the latter I wouldn't recommend for other reasons, though; I don't know about ext4, btrfs and ZFS, but my guess would be that ext4 has static allocation and the others dynamic). Why worry about a problem modern file systems simply don't have?
