[PATCH] linux-2.1.91-pre2 crash fixed

[Rik van Riel <H.H.vanRiel@fys.ruu.nl>]

Hi Linus,

I've found a small typo in mm/filemap.c, which prevented
proper operation of the VM subsystem and, in effect, threw
kswapd in a loop.

In effect, it refused to free buffer memory when it was
_above_ the minimum percentage :)

Rik.
