Subject: LU-6981 target: update obd_last_committed
X-Git-Tag: 2.7.59~42
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=f2cd05463982e2fc17d30c927065266850d55446;p=fs%2Flustre-release.git

LU-6981 target: update obd_last_committed

In tgt_reply_data_init(), it should update
last_committed after analyzing those reply_data,
similar as tgt_server_data_init(), otherwise
obd_last_committed might be smaller than the real
committed transno, and then cause recovery_thread
stuck in check_for_next_transno(), which rely on
the correct last committed transno.
