I remember having used devtmpfs prior to 3.x, and it was working well. For versions prior to 2.6.32, the linux.mk code will set this option that doesn't exist, and the kconfig code of the kernel will simply get rid of it, without any consequences. So I'd like to understand the "why" of this patch :) Thanks! Thomas -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
