  [Feature request] Please implement ATA TRIM command

Status in QEMU:
  Fix Released

Bug description:
  Modern linuxes can use ATA TRIM command on block devices. It will be
  very nice if qemu translates this request to underlying block driver.

  1. So, if I use RAW image (on my case - lvm partition), TRIM inside qemu 
should do TRIM command on my readl HDD
  2. In the future, TRIM command inside qemu will free space inside qcow images.
