And of course I forgot this is an internal API, so this doesn't work
without some of other stuff which isn't ready.
Please ignore...

Le 25/01/2020 12:46, Stephen Kitt a écrit :
Instead of hand-coding the dma_resv_list allocation, use
dma_resv_list_alloc, which masks the shared_max handling. While we're
at it, since we only need shared_count fences, allocate shared_count
fences rather than shared_max.
(This is the only place in the kernel, outside of dma-resv.c, which
touches shared_max. This suggests we'd probably be better off without
it!)
