Disabling tab discarding in Google Chrome

I'm using Chrome version 48.0.2564.23 beta-m (64-bit) and I wanted to disable tab discarding. Elsewhere on the internet people say there is a flag for this (chrome://flags/#enable-tab-discarding) but I cannot find it. Has this option been disabled, renamed? Is it still possible to disable tab discarding?

I had the same problem and finally found a flag named “automatic-tab-discarding” (chrome://flags/#automatic-tab-discarding). So I think the previous flag “enable-tab-discarding” has simply been renamed once the tab discarding behavior was made the default. Which makes sense.

I'd really prefer it to be a regular Chrome option though, instead of an unguaranteed-to-remain-functional flag.

Use --force-fieldtrials=AutomaticTabDiscarding/Disabled as a commandline switch, following these instructions.
