Hi Laura,

There is no advantage to having heap types be a mask. The ion client has
long since dropped the mask. Drop the notion of heap type masks as well.
I know this is the same patch you sent last time, so sorry for not
picking this up then - but I'm curious what "The" ion client is here?
ion_client_create used to take a mask to indicate what heap types it
could allocate from. This hasn't been the case since 2bb9f5034ec7
("gpu: ion: Remove heapmask from client"). "The ion client" probably
should have been "struct ion_client"
Our ion client(s) certainly still use these masks, and it's still
used as a mask within ion itself - even if the relationship between a
mask and a heap type has been somewhat lost.
Where is it used in Ion? I don't see it in tree unless I missed something
and I'm not eager to keep this around for out of tree code. What's the
actual use for this?
Thanks,
Brian
