From 1e7710f3f6563940bb6bbc94aa8eadfd344a86af Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Tue, 4 Apr 2017 13:31:47 +0300 Subject: IB/core: Change completion channel to use the reworked objects schema This patch adds the standard fd based type - completion_channel. The completion_channel is now prefixed with ib_uobject, similarly to the rest of the uobjects. This requires a few changes: (1) We define a new completion channel fd based object type. (2) completion_event and async_event are now two different types. This means they use different fops. (3) We release the completion_channel exactly as we release other idr based objects. (4) Since ib_uobjects are already kref-ed, we only add the kref to the async event. A fd object requires filling out several parameters. Its op pointer should point to uverbs_fd_ops and its size should be at least the size if ib_uobject. We use a macro to make the type declaration easier.
