My F33 system happily hibernates to disk, even with an application that
succeeded in din doing an mlockall().
And it somewhat makes sense. Even my freshly-booted, idle F33 has
$ cat /proc/meminfo
Btw. I do not see Rafael involved. Maybe he can add some insight to

It is unsafe to allow saving of secretmem areas to the hibernation
snapshot as they would be visible after the resume and this essentially
will defeat the purpose of secret memory mappings.
Prevent hibernation whenever there are active secret memory users.
