[PATCH 0/5] use fiddle for Linux-specific APIs

[Eric Wong]

fiddle is distributed with Ruby since 1.9.2 (and the oldest we
support is 1.9.3).  So instead of expecting potential users to
install Ruby development headers and a C compiler, just use
fiddle to save potential users bandwidth and storage space.

We have to define some hard-coded constants, but all of these
constants are architecture-independent and we can trust the
Linux kernel to never break userspace.

Eric Wong (5):
  pipe: avoid loading sleepy_penguin
  use fiddle-based eventfd implementation
  buffer: replace sleepy_penguin with fiddle
  watchable: use fiddle for inotify support
  doc: remove "sleepy_penguin" references
