Instead of unconditionally expiring the timer and calling a long mt_release_contacts(), we can check if some slots are used when the timer expires. We can also remove the timer if we happen to receive all the releases. The logic behind the MT_IO_FLAGS_PENDING_SLOTS could be implemented by counting how many slots are active, but using bits feels slightly more efficient.

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.
