Sorry, I couldn't reply earlier(I am currently on travel). Yes, the ext4
merge looks correct to me. You have taken the latest v4 of the ext4
atomic write series [1].

Due to limited connectivity during my travel, I don't have the access to
the hardware. But as I mentioned the merge looks correct to me and I had
tested those patches earlier on Power and x86.
But I will in general re-test the mentioned fs branch for both XFS and
ext4 once I reach back but I don't think we need to wait for that as the
merge looks good to me.

Also, I noticed that we might have missed to add a Tested-by from
Ojaswin for XFS series here [2]. Although Ojaswin mentioned that he
might also re-test the mentioned FS atomic write branch for both XFS and
EXT4.
