[IB] uverbs: Close some exploitable races
Al Viro pointed out that the current IB userspace verbs interface allows userspace to cause mischief by closing file descriptors before we're ready, or issuing the same command twice at the same time. This patch closes those races, and fixes other obvious problems such as a module reference leak. Some other interface bogosities will require an ABI change to fix properly, so I'm deferring those fixes until 2.6.15. Signed-off-by: Roland Dreier <rolandd@cisco.com>
