Why? Because you've been posting into threads that are way above my pay grade, so I haven't been reading them :/ Anyway, a belated welcome to the mailing list and thanks for the valuable info you've been sharing with us. thanks, very happy to be here as it is also a treasure trove of valuable information :) BTW, based on the content of your posts I'd estimate that you're roughly two years older than I am, which would make you about 41, right? good guess, actually ~35

It doesn't tell you what the menu entry is. It's not always obvious what menu entry corresponds to CONFIG_whatever, and you sometimes have to work your way down the menu looking at the help for each one until you find the one you're looking for. This seems to a problem I run into regularly for things like network drivers. The CONFIG_ variable name usually matches the module name, but but there's often little or no correlation between the CONFIG_ name and the menu entry you use to enable/disable it. -- Grant Edwards grant.b.edwardsYow!

Would be nice if the news item had something like CONFIG_FHANDLE (General setup 'open by fhandle syscalls') The menuconfig paths are subject to change, and the news item will be around for a while.
