Dear Andy, Kees, Will, dear kernel community,
With 5.8-rc3 there is a seccomp related crash which prevents Chromium and
QtWebEngine from starting:
Bug 208369 - seccomp crash with Chromium, QtWebEngine and related browsers: seccomp-bpf failure in syscall 0072
https://bugzilla.kernel.org/show_bug.cgi?id=208369
Reverting to 5.8-rc2 fixes the issue.
Best,
--
Martin

Hi,
It looks like this is from e9c15badbb7b ("fs: Do not check if there is a
fsnotify watcher on pseudo inodes")
Currently being discussed here:

It's a definite problem. I've sent a revert but it hasn't hit lkml yet
for whatever reason.
