As there seems to be no significant outstanding concern about
dax on ext2 at this point, remove the scary EXPERIMENTAL
warning when in use.

Agreed. 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,

'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
