Don't know, but yes, it's probably quite rare. > 2: If it DID happen, rather than 2 copies, could store one inode with 2 > directory entries (hard links) with the 2 names. I don't think you can in an acceptable way find an existing file to reuse when you're about to store a new file -- you'll have to list the directory and iterate through its items to look for a reusable file. (That is, unless you introduce some kind of higher-level index that makes it possible to efficiently list existing files with a given hash.) -- Joel _______________________________________________ ccache mailing list [email protected] https://lists.samba.org/mailman/listinfo/ccache
