Kernel Bug Tracker – Bug 16031
slabinfo description inaccurate (out of date?)
Last modified: 2013-09-10 16:50:14 UTC
"man slabinfo" claims, for example, that the fifth column is "the number of pages with at least one active object", when /proc/slabinfo on my (2.6.32) machine uses it for number of objects per slab. Presumably the format it describes is outdated (example shows version 1.1, current is 2.1).
This is from Ubuntu (Lucid)'s 3.23-1.
As of man-pages 3.51 this is still the case, but perhaps the correct thing to do being it a kernel file should be to add a note directing users to read current /usr/src/linux/Documentation/vm/slub.txt and/or play with /usr/src/linux/tools/vm/slabinfo.c
