One possible option would be to list the similar bugs at the start of the bug report. See also: KASAN: use-after-free Write in hiddev_disconnect https://syzkaller.appspot.com/bug?extid=784ccb935f9900cc7c9e Then we could just copy and paste to the "#syz dup:" command. The bitmap_port_list() stuff was reported something like 15 times so it was really complicated to track. Hopefully if it were easier to mark things as duplicate that would help. regards, dan carpenter
