Do you want my ack or should I just merge this patch? Please do not merge it. The whole DAX path is still a mess and should not be elevated to non-EXPERMINTAL state in this form.

Hi Christoph, "a mess" is tough to work with. What work remains before we can lift the warning? -Eric

Hi Christoph, 'still a mess' isn't all that useful for figuring out what still needs to be done and splitting up the work. Do you have items beyond my own list below? - still arguing over what exactly FALLOC_FL_ZERO_REINIT_WHATEVER_PONIES should be doing - no reflink support, encompassing: - hwpoison from mmap regions really ought to tell the fs that bad stuff happened - mm rmap can't handle more than one owner --D

We need to sort out the whole story of how pmem/nvdimm is actually treated, because what we have right now is not sustainable at all.

As there seems to be no significant outstanding concern about dax on ext2 at this point, remove the scary EXPERIMENTAL warning when in use. Signed-off-by: Eric Sandeen <sandeen@redhat.com> --- fs/ext2/super.c | 2 -- 1 file changed, 2 deletions(-)
