GEM - radeon cs ioctl deadlock

[Jerome Glisse]

So we are facing a deadlock with the radeon cs ioctl. When a buffer is given
a name (with flink) we could endup with 2 handle pointing to the same
object (flink object and open it from same file descriptor). Would it be ok
if i change gem open to first look if we already have an handle for the
object and to use that handle instead of creating a new one ? Or could
this break intel driver ?

Cheers,
Jerome
