From 6b73597e7062118c0549c2702bfb7d273518c906 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 26 Sep 2005 13:53:25 -0700 Subject: [IB] uverbs: ABI-breaking fixes for userspace verbs Introduce new userspace verbs ABI version 3. This eliminates some unneeded commands, and adds support for user-created completion channels. This cleans up problems with file leaks on error paths, and also makes sure that file descriptors are always installed into the correct process.
