[Qemu-devel] [PATCH for-2.0] iscsi: always query max WRITE SAME length

Max WRITE SAME length is also used when the UNMAP bit is zero, so it should be queried even if LBPWS=0. Same for the optimal transfer length. However, the write_zeroes_alignment only matters for UNMAP=1 so we still restrict it to LBPWS=1. Signed-off-by: Paolo Bonzini pbonz...@redhat.com ---
