Well, the idea is to get it done in the VFS layer. reiserfs, ext3, and
probably the other journaled filesystems could keep track of the last
transacation and inode was involved with, making the softupdate style
fsync(file) to commit a rename easy.

But, ext2 and the normal filesystems don't have it quite so good.
