I saw this patch appear in kernel v3.12-rc1, and it's nice since it's exactly
what we need. So needed that we proposed it in 2010:
http://marc.info/?l=linux-kernel&m=127425650923757&w=2
http://marc.info/?l=linux-kernel&m=127599718024364&w=2

Is this patch inspired by Ulfs patch? (I can see the code is different,
but the cmdline argument is the same for example.) Some credit
could have been proper in that case.

Just asking: sometimes wheels do get reinvented.

Yours,
Linus Walleij
