Not using QEMU_ALIGN_DOWN despite patch 3?
Looks like I missed that on the rebase. Can fix if there is a reason for
a respin.
Since Stefan acked this, I'm applying the patch and fixing it to use
QEMU_ALIGN_DOWN.

Hi,
I came across a sort of regression we introduced with the dropping of head and
tail
of an unaligned discard.
The discard alignment that we use to trim the discard request is just a hint.
I learned on the equallogics that a page (which is this unusal 15MB large) is
unallocated even if the discard happens in pieces. E.g. in slices of 1MB
requests.
From my point of view I would like to restore the old behaviour. What do you
think?
Thanks,
Peter
