I see there is some discussion with Bart's patch with respect to SDMA. So I guess it might take a while to merge his patchset. How about doing this? - add this with 'ib_' prefix into 4.10-rc. - followed by cherry pick this commit in linux-rdma tree. When Bart rebase it, changes of this fix will automatically get converted from ib_ to dma_. So shall I send patch for 4.10-rc with 'ib_' prefix? ��.n��������+%������w��{.n�����{���fk��ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
