Last version v4 of these patches was sent by Colin Cross a long time ago [1]
and [2]. At the time, these patches were not merged, and it looks like they
just fell off the radar since.
In our efforts to run Android on mainline kernels, we realised that since past
some time, this patchset is needed
ures the pagelist is also freed on release.
Thanks for your patch.

very appealing name, so suggestions are very welcome!
Benjamin Gaignard (1):
cenalloc: a sample allocator for contiguous page allocation
Sumit Semwal (3):
dma-buf: Add constraint
c_buffer_free to free the buffer if refcount reaches zero;
** IMPORTANT**
This mechanism of delayed allocation based on constraint-enablement will work
*ONLY IF* the first map_attachment() call is made AFTER all attach() calls are
done.
