This notice fills my boot logs with scary-looking asterisks but doesn't
really tell me anything. Let's just remove it; validation errors
are already reported separately, so this is just a redundant list of
filesystems.
$ dmesg | grep VALIDATE
[ 0.306256] *** VALIDATE tmpfs ***
[ 0.307422] *** VALIDATE proc ***
[ 0.308355] *** VALIDATE cgroup ***
[ 0.308741] *** VALIDATE cgroup2 ***
[ 0.813256] *** VALIDATE bpf ***
[ 0.815272] *** VALIDATE ramfs ***
[ 0.815665] *** VALIDATE hugetlbfs ***
[ 0.876970] *** VALIDATE nfs ***
[ 0.877383] *** VALIDATE nfs4 ***

Hi Andrew,
Can you pick this up in -mm?
Thanks!

Excellent, these messages haven't been useful in helping users diagnose
problems and they look quite noisy considering how mundane they are.
