Subject: LU-18813 osd-wbcfs: make dt_last_seq_get() optional
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=bae082e9c4f5ecdfb5642462470200c91ac94885;p=fs%2Flustre-release.git

LU-18813 osd-wbcfs: make dt_last_seq_get() optional

Allow osd-wbcfs to leave this unimplemented for
now. Once we track object mapping internally,
we can implement this.

Fixes: 373b76b345b5 ("LU-17658 fid: check on disk sequence before allocating to osp")
Test-Parameters: trivial
