@adisky excellent, can we remove the in-tree in kubernetes 1.17?

[adisky]

@dims trying hard for removal in v1.17

[hogepodge]

Oh please, yes. CSI migration is the only thing blocking this? @adisky if the code isn't removed (or the storage code stays) we also have to switch to using the utils/mount package rather than the duplicated code we used for the staging patch.

@kendallnelson

[ramineni]

@hogepodge Still mount package PR is not yet merged in utils package (not updated from long time), keeping an eye on that as well , if removal not completed in time , Ill submit a PR to use new mount package if merged

[kendallnelson]

Looks good to me, but my opinion definitely shouldn't have the weight that other's do.

[adisky]

removed WIP, some fields are still TODO, we will update them as per our progress.
