witness: reversal: vmmaplk inode
Status: fixed on 2019/12/18 19:18
Reported-by: syzbot+0ab93519af8f3dbfb136@syzkaller.appspotmail.com
Fix commit: Use separate rwlock initializations for userland ("vmspace") and kernel maps. This lets witness know that these really are different classes avoiding false positives when detecting lock order reversals.
