Tracking down all callers of blk_pwrite_zeroes is not as trivial as in
the previous patches.  But the very first one I checked:
 block.c: create_file_fallback_zero_first_sector()

is neither marked coroutine_fn, nor does it have the "if
(qemu_in_coroutine())" guard.  And block.c is not touched in this
patch series, per the diffstat in 0/26.  Am I missing something?
