The reason why I've been silent is because I haven't had a chance to do was a test run with DAX, because up until recently I wasn't able to run a DAX regression test run. (That's because of the CONFIG_KASAN incompatibility with CONFIG_ZONE_DEVICE that caused the kernel to instantly blow up on boot if I tried to enable emulated /dev/pmem devices.) I just kicked off a DAX test ("gce-xfstests -c dax -g auto") with CONFIG_KASAN disabled, and I expect it shouldn't show up anything concerning. So assuming nothing surprising pops up, yes it should be merged at the next merge window. - Ted
