I want to enable trim support rbd see:

I think we can generally enable it it doesn't harm.
Where can we do this?(which function)
That seem to be a highly experimental feature - only used by ide and scsi block

discard_granularity has hardoced limits, and is not really documented :-/
Just for IDE ;-) Who uses IDE today? ;-) For SCSI there are no limits.
I'll check this.
