who in the right mind would use the keyword REQ for describing successfull
allocations? i think if this is really the case, it should be changed to SUCC
and, if possible, REQ, describing the total number of requested allocations,
should be added.
just my 0.02$.
thanks for clearing thinks up for me. unfortunately the vmstat(8) man page
doesn't come with any description for the -z output. it would be nice to have
sections for every vmstat mode, like in the procstat(1) man page.
cheers.
