Are you sure this is 2685 ? As of 2658, I think uverbs now starts at minor 192 rather than 128. 2658 Modified: gen2/trunk/src/linux-kernel/infiniband/core/uverbs_main.c Log: Fix order of cleanup in module unload. Move first minor from 128 to 192. -- Hal > > -JE > > On Wed, 2005-06-22 at 19:02 -0700, Roland Dreier wrote: > > Josh> I'm trying to figure out how to do an RDMA write with > > Josh> immediate data.
