This patch set introduces a new file system for the delivery of pollable events through file descriptors. To the detriment of debugability, pollable objects are a nice adjunct to nonblocking/epoll/event-based servers.
The pollfs filesystem abstraction provides better mechanisms needed for creating and maintaining pollable objects. Also the pollable futex approach is far superior (send and receive events from userspace or kernel) to eventfd and fixes (supercedes) FUTEX_FD at the same time. The (non) blocking and object size (user <-> kernel) semantics and are handled internally, decoupling the core filesystem from the "subsystems" (mere push and pop operations). Currently implemented waitable "objects" are: signals, futexes, ai/o blocks and timers.
