AFAICT. I don't see why it wouldn't; on a rename, the inode's i_pos changes but its i_ino stays the same, right? Do you have any objection to making the use of a directory logstart cache a mount option that defaults to off? It seems a shame to penalize everyone - particularly embedded systems - with the overhead of such a cache when FAT-backed-NFS seems to be such a small percentage of use cases. ------------------------------------------------------------------------ Steven J.
