If a resync/recovery/check/repair is interrupted for some reason, it can be useful to know exactly where it got up to. So in that case, do clear curr_resync_completed. Initialise it when starting a resync/recovery/... instead. Signed-off-by: NeilBrown <redacted> --- drivers/md/md.c | 7 +++++-- 1 files changed, 5 insertions(+), 2 deletions(-)
