fcntl: expose write-stream management to userspace
0030fa2 
Wire up the userspace interface for write stream management via three
new fcntls.
F_GET_MAX_WRITE_STREAMS: Returns the number of available streams.
F_SET_WRITE_STREAM: Assign a specific stream value to the file.
F_GET_WRITE_STREAM: Query what stream value is set on the file.

Application should query the available streams by calling
F_GET_MAX_WRITE_STREAMS first.
If returned value is N, valid stream values for the file are 0 to N.
Stream value 0 implies that no stream is set on the file.
Setting a larger value than available streams is rejected.

iomap: introduce and propagate write_stream
3a9e3c6 
Add a new write_stream field to struct iomap. Existing hole is used to
place the new field.
Propagate write_stream from iomap to bio in both direct I/O and buffered
writeback paths.

xfs: enable userspace write stream support
fc819ff 
Implement support for userspace controlled write-streams.

Add a new i_write_stream field in xfs inode (note: existing hole is
used), and use that to implement write stream management file operations.
