RDMA: Mark if create address handle is in a sleepable context
Introduce a 'flags' field to create address handle callback and add a flag that marks whether the callback is executed in an atomic context or not. This will allow drivers to wait for completion instead of polling for it when it is allowed. Signed-off-by: Gal Pressman <[email protected]> Signed-off-by: Jason Gunthorpe <[email protected]>
