[PATCH 0/7] Tests for sync infrastructure

[Emilio López]

Hello everyone,

This is a series of tests to exercise the sync kernel infrastructure. It is
meant to be a test suite for the work Gustavo has been doing to destage it.

These tests were originally part of a battery of tests shipping with
Android's libsync that were rewritten to use the new userspace interfaces.

An older version of this set was sent as an RFC series back in March. Now
that the framework has been destaged, I'm resending them with a few
changes - some tests were removed, and some bugs were squashed. See [0]
if you wish to see the the old set.

As usual, all comments are welcome.

Cheers!
Emilio
