Meant 4.21. But on reflection this is perhaps excessively cautious.

The page cache and most shrinkable slab caches hold data that has been
read from disk, but there are some caches that only cache CPU work,
such as the dentry and inode caches of procfs and sysfs, as well as
the subset of radix tree nodes that track non-resident page cache.
Currently, all these
