Shilong, do we also need the LU-13845 patch to make this work properly?

[Wang Shilong (Inactive)]

adilger you mean LU-13846?

[Andreas Dilger]

Yes, sorry for the confusion. I'm wondering if patch https://review.whamcloud.com/39565 "LU-13846 llite: move iov iter forward by ourself" is also needed for correct operations, and whether it makes sense to merge them together.

[Wang Shilong (Inactive)]

I think they are different problems, actually this ticket fixed leftover from LU-13697 and unfortunately we did not make it once in LU-13697
