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
