It can avoid problems on NFS even if you have less than 2^32 files, since NFS uses 64-bit fileids and is not required to use the values 0, 1, 2, 3... for files. In Amazon EFS for example every fileid is > 2^32 and there's no guarantee that two files won't map to the same 32-bit inode # (pre-ino64, we simply reduced the fileid mod 2^32 to generate an inode #). -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
