Hi Bernd,

As far as I can see, Joanne's patches enable large folios for regular files.
Here we operate on directories, which are initialized through fuse_init_dir()
and so do not use large folios. In any case, these patches switch to using
the relevant folio helpers, which would get us closer to using large folios
in the readdir cache if that's eventually desired.

Thanks,
Tal
