field to set would create a cascade of churn
throughout kernel (and invariably many callers won't need the new field
initialized, so you keep passing 0 for more and more fields).

Unfortunate that you cannot just include blk_types.h in fs.h; but
vma_is_dax() ruins that for us sinc

Ordering aside, you cannot split more than once. So your proposed fix
to insert at head isn't valid because you're still implicitly allocating
more than one bio from the bioset which could cause deadlock in a low
memory situation.
SFS change that broke reencryption (and all other
functionality that requires reloading a dm-crypt DM table).
