Title:
DISCARD support for Crypto Block Devices
Status in QEMU:
Expired
Bug description:
It appears that running `fstrim` or similar is useless when the VM is
on a LUKS-encrypted device using QEMU's native LUKS support.
Looking at the source, it seems that block/crypto.c lacks an
implementation for bdrv_co_pdiscard, which probably needs to delegate
to a per-crypto type discard helper.
