It's not easy for us to reproduce the fsnotify() lockup issue, and actually we still don't have an easy & reliable way to reproduce it. According to our tests, v4.16 doesn't have the issue. And v4.15 doesn't have the issue either, if I recall correctly. I only know the issue happens to v4.14.x and 4.13.x kernels Thanks, -- Dexuan
