After a renewed interest in futex from several groups who are trying to extend the interface (i.e. futex wait multiple, futex swap, variable-sized futexes), alongside failed attempts to solve longstanding issues that cannot be solved under the current interface, Thomas Gleixner is convinced a new implementation of futex is necessary. This topic will collect feedback on the work being done to design this new interface and discuss next steps to get this effort upstream.
