4.4 doesn't have the statx() system call, which is the usual source of "can't 
find file" -- when we ask for the file's status with the statx() system call, 
under 4.12 with incorrect system call filtering, we get an unexpected error 
code that leads us to think the file doesn't exist.

The two other important filesystem changes that applied to 5.10 (use of 
renameat2() and O_TMPFILE) should have proper fallback codes.

Still, can you try to run outside of a docker container to see if the problem 
goes away? If it does, can you run your container without system call 
filtering? Or on a real (non-unionfs) filesystem?
