Subject: ext4 support iopoll

hi,

While testing iouring in ext4, we find ext4 does not support .iopoll yet, since
commit "ext4: introduce direct I/O write using iomap infrastructure", seems that
ext4 can support iopoll as well, just add a ".iopoll = iomap_dio_iopoll,".
So I wonder is there any special reason that ext4 does not have have this iopoll
interface? Thanks.

Regards,
Xiaoguang Wang
