Hi, I have a question about (1) in the following RFC: http://www.spinics.net/lists/linux-rt-users/msg15082.html Does Upstream accept such a patch? < Overview > My environment (v4.6-rc5 on arm64 / r8a7795) has similar situation when dma_free_coherent() is called. < For example (The buffer size is 1024 bytes.) > - Sometimes the function spends about 8 msecs (worst-case). - If I modified the value such the patch, sometimes the spend time is about 1 msecs (worst-case). So, I would like to know that upstream accepts such a patch. < Remarks > I also tried both the (1) and (2) patches on my environment. However, kernel stopped on the way.
