The work mcast_task can re-queue itself, so instead of doing cancel && flush_workqueue, that still can leave a queued task on the air, use cancel_delayed_work_sync. Also, no need to use lock over the cancel, the original lock was due to bit assignment setting (IPOIB_MCAST_RUN) that is not in use anymore.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
