[ discovered by alexey on #kernelnewbies ]

One thing we should do is make sure the buffer cache code sets
the referenced bit on pages, so we don't recycle buffer cache
pages early.

This should leave more space for the buffercache and lead to us
reclaiming the (now unused) space in the dentry cache instead...

regards,

Rik
