Subject: [PATCH rdma-next 00/14] Refactoring FD usage
Date: Wed, 8 Jan 2020 19:21:52 +0200 [thread overview]
Message-ID: <1578504126-9400-1-git-send-email-yishaih@mellanox.com> (raw)
This series refactors the usage of FDs in both IB core and mlx5 driver.
It includes:
- Simplify destruction of FD uobjects by making them pure uobjects and use
a generic release method for all struct file operations.
- Make ib_uverbs_async_event_file into a uobject.
- Improve locking in few related areas.
- Simplify type usage for ib_uverbs_async_handler().
This refactoring series may be followed by some other series that will allow
the async FD to be allocated separately from the context and then enables
having the alloc_context command over ioctl.
