Hi,
I have previously posted this as an RFC [1] but there didn't seem to be
any objections other than some requests to reorganize the changes in
a slightly different way so I am reposting the series and asking for
inclusion.
This is a follow up on top of [2]. The patch 1 cleans up the code a bit.
I haven't seen any real issues or bug reports but conceptualy ignoring
the maximum eligible zone in get_scan_count is wrong by definition. This
is what patch 2 does. Patch 3 removes inactive_reclaimable_pages
which was a kind of hack around for the problem which should have been
addressed at get_scan_count.
There is one more place which needs a special handling which is not
a part of this series. too_many_isolated can get confused as well. I
already have some preliminary work but it still needs some testing so I
will post it separatelly.
