[openib-general] Re: [PATCH] kDAPL: remove typedef DAT_CONTEXT

Mostly committed in revision 2515. 

I didn't remove DAT_UPCALL_NULL and DAT_UPCALL_SAME. DAT_UPCALL_NULL 
is provided as a convenience to the consumer. I think it is useful, but 
I'm willing to hear other opinions. The provider's implementation of 
dat_evd_modify_upcall() should check for the DAT_UPCALL_SAME value. 
The fact that it doesn't is a bug.
