> Is this fixed by Thomas's mlock patches?

The issue is gone on latest -nightly branch.

BTW, the Thomas's patch Chris mentioned is following one?
But it's not fixed by this patch by double checking with this patch.
Anyway the case is passed now, close it.

    lib: add a function to lock memory into RAM

    Add a function to lock memory into RAM and use it in the
    gem_tiled_swapping test to reduce the amount of allocated memory
    required to force swapping. This also reduces the amount of time
    required for the test to complete, since the data set is smaller.
