An NTFS SD can be up to 64kiB in size. That allows for up to about 1,800 ACEs, although I have not seen that many. However, I have seen some ACLs with several hundred ACEs. ACEs are around 30 bytes in length (S-1-5-21-x-y-z-rid, plus perms etc) -- Regards, Richard Sharpe (何以解憂？唯有杜康。--曹操) -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
