git: kernel - vm - Change inactive target to 1/4 memory instead of 1/2 memory.

[Matthew Dillon]

:On my troublesome 2GB machine, the inactive memory is now ~= 750M, which
:is about 1/3 of RAM, quite far from the 1/4 target.

    It's just a target for the pageout daemon, it isn't something the
    machine tries to hold itself to.

    Guys... everyone.  Please don't try to interpret the values for
    the active & inactive queues.  Even a good chunk of the analysis of
    the swap space use is wrong.  There's absolutely nothing wrong with
    the machine paging stuff out to swap.  The issue is only whether it
    does so to the degree that later pageins effect performance.

    Avalon, for example, usually has 200-400MB of idle data swapped out
    which it basically never touches.  It doesn't effect avalon's
    performance.
