Dear sir,
 
When learning and testing DRBD 8.4.0, I could not find where it applies active log to bitmap when up a resource after a crash.
 
While DRBD 8.3.9 do it in drbd_nl_disk_conf()  calls drbd_al_read_log(), then drbd_al_apply_to_bm().
 
So, is there anything I have not caught up? The code is download from http://oss.linbit.com/drbd/8.4/drbd-8.4.0.tar.gz
 
Any hints are very appreciated!
 
Regards!

That moved to user space. See the "apply-al" sub-command of drbdadm.
