Subject: tools/vm/slabinfo: add sorting info to help menu
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cbf800d9c7fb38d953ba8ae1bd27a6382114c32e;p=linux.git

tools/vm/slabinfo: add sorting info to help menu

Passing more than one sorting option has undefined behaviour.

Add an explicit statement as such to the help menu, this also has the
advantage of highlighting all the sorting options.
