----- Forwarded message from Or Gerlitz <ogerlitz-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org> -----
So what exact capability is under the spot here? and how it's related
to a certain HCA driver and not to the kernel uverbs layer?
----- End forwarded message -----
ibv_open_device fail when opening the hca many times. ucma_init call
this api a-priori on all the devices for any process that use the
library. The patch remove this a-priori open and open the device only
when verbs are really needed. I do not think its issue at the verbs
but more issue in how the librdmacm use the verbs.
