What about this?

### Statedump support for gfapi based applications

*Notes for users:*
gfapi based applications now can dump state information for better trouble
shooting of issues. A statedump can be triggered in two ways:

1. by executing `gluster volume statedump <VOL> client <HOST>:<PID>`
   on one of the Gluster servers
   
   - `<VOL>` should be replaced by the name of the volume
   - `<HOST>` should be replaced by the hostname of the system running the
     gfapi application
   - `<PID>` should be replaced by the PID of the gfapi application
   
1. through calling `glfs_sysrq(<FS>, GLFS_SYSRQ_STATEDUMP)` within the
   application
   
   - `<FS>` should be replaced by a pointer to a `glfs_t` structure

All statedumps (`*.dump.*` files) will be located at the usual location,
on most distributions this would be `/var/run/gluster/`.

*Limitations:*
It is not possible to trigger statedumps from the Gluster CLI when the
gfapi application has lost its management connection to the GlusterD
servers.

GlusterFS 3.10 is the first release that contains support for the new
`glfs_sysrq()` function. Applications that include features for
debugging will need to be adapted to call this function. At the time of
the release of 3.10, no applications are known to call `glfs_sysrq()`.

*Known Issues:*

Poornima, do you have anything to add/change?

Thanks,
Niels
