I just wanted to make sure that the community is on-board in reviewing the patch and making decisions.

They are at [1], [2] and [3]. But, I guess it is not clear what this work item means exactly. I can change it as follows: > > "Change IO barriers to use 'DMB' instruction for Armv8-a" > > The patch itself is trivial. But, it is a basic change affecting all the drivers for Arm platforms. So, I would like to call out everyone's attention. > > [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=22ec71615d824f4f11d38d0e55a88d8956b7e45f > [2] https://www.youtube.com/watch?v=i6DayghhA8Q > [3] https://www.cl.cam.ac.uk/~pes20/armv8-mca/ > > > > >
