We must do so before we call drbd_flush_workqueue(), as at least the callback w_restart_disk_io() may wait for resync progres, and would otherwise deadlock. drbd_finish_peer_reqs() may again populate that cache, which will then potentially be stale after the next resync handshake and bitmap exchange, we have to do it again after that. A stale resync lru cache causes no harm but ugly messages like this: BAD! sector=196608s enr=6 rs_left=-256 rs_failed=0 count=256 cstate=SyncTarget Signed-off-by: Philipp Reisner Signed-off-by: Lars Ellenberg --- Reading git-diff-tree failed
