Re: [PATCH 1/2] [RFC PATCH v6] dmabuf-sync: Add a buffer synchronization framework

+EXPORT_SYMBOL(is_dmabuf_sync_supported);

_GPL ?

I would also prefix it with 'dmabuf_is_sync_supported' just to make
all of the libraries call start with 'dmabuf'

Seems better. Will change it to dmabuf_is_sync_supported, and use
EXPORT_SYMBOL_GPL.

One thing thought - while I suggest that you use GPL variant
I think you should check who the consumers are. As in, if nvidia
wants to use it it might make their lawyers unhappy - and in turn
means that their engineers won't be able to use these symbols.

So - if there is a strong argument to not have it GPL - then please
say so.
