Changes since RFC: o rebase over v5.6 o fixed return code for ioctl() I've sent RFC a while ago and it probably was very late in release cycle to catch any attention: https://lkml.kernel.org/r/20200121162145.166334-1-dima@xxxxxxxxxx While waiting for rc1, I've changed my mind that it's RFC material and sending it as PATCHv1 instead.
