tmpfs sizing broken in 4.4-rc*

tmpfs sizing broken in 4.4-rc*

[Andi Kleen]

Hi,

It seems on 4.4-rc2 something is wrong how tmpfs is sized by default.

On a 4GB system with /tmp as tmpfs I only have an 1MB sized /tmp now. Which
breaks a lot of stuff, including the scripts to install new kernels.

When I remount it manually with a larger size things works again.

I haven't tried to bisect or debug it, but I'm reasonably sure the
problem wasn't there with 4.3.

Never mind. I did some more experiments and tmp seems to be back
to the expected size now after some experiments/reboots. Must have been some
fluke or a rogue script.
