As Josh mentioned in comment #2, finding a sleepy context was the main holdup
here. Kernels >= 3.5 have a feature called "task_work" that we're now using to
provide that sleepy context.
There are still missing features when compared to the old utrace-based uprobes
(like uretprobes), but we now support the upstream inode-based uprobes. Any
remaining bugs in the new inode-based uprobes support we can track separately.
