assert "curproc->p_kd == NULL" failed in kcov.c
Status: fixed on 2020/08/15 01:06
Reported-by: syzbot+1252e696865efc29b767@syzkaller.appspotmail.com
Fix commit: 2fa3abdda1a4 When detaching common remote coverage, do not clear any fields. Instead, let kr_free() do the work. Otherwise a thread currently inside a remote section could end up not decrementing the number of ongoing sections while exiting the same remote section.
