i browsed few kernel sources and that's what i see:

1) vm.filemin/filemax/execmin/execmax etc. are forced from only one side.
i.e. when there's less buffer cache than filemin set active some pages are
reactivated.

but when making pages inactive there is no priority based on
filemax/execmax etc. taken.

so these settings basically doesn't work - which is well shown on my
example where i've set filemin 1% and filemax 2% and still have flooded
memory when large file I/O

this is IMHO broken by general and must be fixed.
