Partially. No more error but the watcher have no effect like on
emacs-27.
helm-find-files is caching the directories it visits and for each
directory is adding a watcher, for example on emacs-27:

M-x helm-find-files => navigate to /sudo::/home/me/tmp/ directory:

foo.txt
bar.txt
baz.txt

Now from a shell:

touch ~/tmp/test.txt

M-x helm-find-files => navigate to /sudo::/home/me/tmp/ directory:

foo.txt
bar.txt
baz.txt
test.txt

test.txt is not added with emacs-28, that's mean the watcher didn't
notify helm to remove tmp directory from cache.

Thanks.
