name [28]	File name. If the file is the root directory of the server the name must be /.
uid [28]	Owner name.
gid [28]	Group name.
qid.path [4]	File server's identification for the file. See Inferno File Protocol, Styx.
qid.vers [4]	Version number for given path. See Inferno File Protocol, Styx.
mode [4]	Permissions and flags. The mode contains permission bits as described in Inferno Devices and `16r80000000` if this file is a directory.
atime [4]	The last access time. The `atime` field records the last read of the contents; it is also set whenever `mtime` is set. For a directory, `atime` is set by an attach, walk, or create, all whether successful or not. The value is measured in seconds since the epoch (Jan 1 00:00 1970 GMT).
mtime [4]	The last modification time. The `mtime` field reflects the time of the last change of content. For a plain file, `mtime` is the time of the most recent create, open with truncation, or write; for a directory it is the time of the most recent remove, create, or `wstat` of a file in the directory. The value is measured in seconds since the epoch (Jan 1 00:00 1970 GMT).
length [8]	Length of file in bytes. Directories and most files representing devices have, by convention, a length of 0.
type [2]	See discussion of devtype in Inferno File Protocol, Styx.
dev [2]	See discussion of dev in Inferno File Protocol, Styx.


name	The `name` can be changed by anyone with write permission in the parent directory. It is an error to change the name of a file to that of an existing file.
mode and mtime	The `mode` and `mtime` can be changed by the owner of the file. The directory bit cannot be changed by a wstat. All the other defined permission and mode bits can be change.
gid	The `gid` can be changed: by the owner if also a member of the new group. (See Inferno File Protocol, Styx for more information about permissions and users for users and groups).
