Caching of reads

Good afternoon,

I've checked the documentation and list archives and I can't find
anything which refers to my problem...

It seems as if reads from a JFFS2 file system are not being cached as we
would expect, for instance this small script:

while true ; do
sleep 1

causes a read from the flash every time the sleep is executed. This is
true even if the fs is mounted read only.

This is with a 2.4.14 kernel (and the JFFS2 therein), does anyone have
any clue as to what might be going on?

Thanks IA,
