--- Comment #4 from PauAmma <paua...@gundo.com> ---
Is this still applicable? That description now reads:
BUS_DMA_ALLOCNOW Pre-allocate enough
resources to handle at
least one map load
operation on this tag. If
sufficient resources are
not available, ENOMEM is
returned. This should not
be used for tags that only
describe buffers that will
be allocated with
bus_dmamem_alloc(). Also,
due to resource sharing
with other tags, this flag
does not guarantee that
resources will be
allocated or reserved
exclusively for this tag.
It should be treated only
as a minor optimization.
