@kawasaki
fs: add a new user_write_streams() callback
4df3436 
so that filesystem can control number of write streams for user space.

Signed-off-by: Kanchan Joshi <[email protected]>
@kawasaki
fs: add the interface to query user write streams
82e8ec9 
Add new fcntl F_GET_MAX_WRITE_STREAMS.
This returns the numbers of streams that are available for userspace.

And for that, use ->user_write_streams() callback when the involved
filesystem provides it.
In absence of such callback, use 'max_write_streams' queue limit of the
underlying block device.

Signed-off-by: Kanchan Joshi <[email protected]>
@kawasaki
fs: add a write stream field to the inode
d26c898 
Prepare for supporting per-inode write streams.
Part of the existing 32-bit hole is used for the new field.

Signed-off-by: Kanchan Joshi <[email protected]>
@kawasaki
fs: propagate write stream
a4466de 
bio->bi_write_stream is not set by the filesystem code.
Use inode's write stream value to do that.

Signed-off-by: Kanchan Joshi <[email protected]>
@kawasaki
fs: add set and query write stream
fcf2b66 
Add two new fcntls:
F_GET_WRITE_STREAM - to query the write-stream on inode
F_SET_WRITE_STREAM - to set the write-stream on inode

Application should query the available streams by calling
F_GET_MAX_WRITE_STREAMS first.
If returned value is N, applications can choose any value from 1 to N
while setting the stream.
Setting the value 0 is not flagged as an error as that implies no
stream.
But setting a larger value than available streams is rejected.
