Hi,
the above commit:
commit d05aa8bb4a8b6aa9a915ec5074fb12ae632d2323
Author: Eric Blake <ebl...@redhat.com>

block: Add .bdrv_co_pwrite_zeroes()
introduces a regression (at least for me).
The Limits from the iSCSI Block Limits VPD have no requirement of being a power
of two.
We use Dell Equallogic iSCSI SANs for instance. They have an internal page size
of 15MB. And
they advertise this page size as max_ws_len, opt_transfer_len and
opt_discard_alignment.
I think we cannot assert that that these alignments are a power of 2.
Peter
