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
