Richard Yao 8170d28126 Return correct type and offset from zfs_readdir ... zfs_readdir() is used by getdents(), which provides a list of all files in directory, their types and an offset that be used by llseek() to seek to the next directory entry. On Solaris, the first two directory entries "." and ".." respectively have offsets 1 and 2 on ZFS while the other files have rather large numbers. Currently, ZFSOnLinux is giving "." offset 0 and all other entries large numbers. The first entry's next entry offset points to itself, which causes software that uses llseek() in conjunction with getdents() for filesystem navigation to enter an infinite loop. The offsets used for each directory entry are filesystem specific on all platforms, so we can fix this by adopting the Solaris behavior. Also, we currently report each directory entry as having type 0 (???). This is not wrong, but we can do better. getdents() on Solaris does not appear to provide this information, but it does on Linux and Mac OS X do. ZFS provides easy access to type information in zfs_readdir(), so this patch provides this as well.
