122  * When a Tfoo request comes over the wire, we decode it
123  * (pack.c) from wire format into a request laid out in
124  * a "union l9p_fcall" object.  This object is not in wire
125  * format, but rather in something more convenient for us
126  * to operate on.
127  *
128  * We then dispatch the request (request.c, backend/fs.c) and
129  * use another "union l9p_fcall" object to build a reply.
130  * The reply is converted to wire format on the way back out
131  * (pack.c again).
132  *
133  * All sub-objects start with a header containing the request
134  * or reply type code and two-byte tag, and whether or not it
135  * is needed, a four-byte fid.
136  *
137  * What this means here is that the data structures within
138  * the union can be shared across various requests and replies.
139  * For instance, replies to OPEN, CREATE, LCREATE, LOPEN, MKDIR, and
140  * SYMLINK are all fairly similar (providing a qid and sometimes
141  * an iounit) and hence can all use the l9p_f_ropen structure.
142  * Which structures are used for which operations is somewhat
143  * arbitrary; for programming ease, if an operation shares a
144  * data structure, it still has its own name: there are union
145  * members named ropen, rcreate, rlcreate, rlopen, rmkdir, and
146  * rsymlink, even though all use struct l9p_f_ropen.
147  *
148  * The big exception to the above rule is struct l9p_f_io, which
149  * is used as both request and reply for all of READ, WRITE, and
150  * READDIR.  Moreover, the READDIR reply must be pre-packed into
151  * wire format (it is handled like raw data a la READ).
152  *
153  * Some request messages (e.g., TREADLINK) fit in a header, having
154  * just type code, tag, and fid.  These have no separate data
155  * structure, nor union member name.  Similarly, some reply
156  * messages (e.g., RCLUNK, RREMOVE, RRENAME) have just the type
157  * code and tag.
