[PATCH v2 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.

This is the second iteration of the test suite. Main changes over v1 are
a reworked Makefile and small code style fixes.

If you are testing this on v4.9-rc1, do note that the last test will
currently fail due to a regression[0].

As usual, all comments are welcome.

Cheers!
Emilio
