Unfortunately I have another showstopper. Sadly I missed it until now because
internally we were more worried of issues which were kind of direct problems
for us and I went to deep instead of spending more time reviewing it breath

Priority argument was dropped from the fanotify_init syscall, and since it is
a syscall once released it is set in stone. Without the priority argument, how
are multiple clients supposed to be ordered?

Co-existence between multiple clients was something which was supposed to be
designed in from the start. Use cases like hierarchical storage management,
anti-malware and content indexing should all be able to co-exist. Without a
priority argument I do not see how it can be assured HSM sees the perm event
before anti-malware, and content indexing after both of them? If there was any
discussion about dropping priority I missed it. :(
