RFC: 2.4 VM statistics - top

RFC: 2.4 VM statistics - top

[Rik van Riel]

Hi,

the following patch adds an extra line to the memory output of top,
displaying the Linux 2.4 VM statistics as follows:

  6:26pm  up 24 days,  1:38,  9 users,  load average: 0.02, 0.16, 0.38
90 processes: 89 sleeping, 1 running, 0 zombie, 0 stopped
CPU states:  1.5% user,  1.2% system,  0.0% nice, 97.2% idle
Mem:   174212K av,  165104K used,    9108K free,       8K shrd,   50552K buff
                     51220K actv,   74172K in_d,     300K in_c,      32K target
Swap:  208804K av,  118164K used,   90640K free                   75132K cached

Any objections to adding this patch to the code base ?

regards,

Rik
